Actually a pretty good start to a list, I would add:
Make Maladict Dr past two applications.
Defensive Dispel: could be two stack second Dispel having a longer CD potentially giving healers a choice.
No slow should be greater than frost mage cone of cold (nothing higher than 50 aside from this ability)
Class changes:
Shaman - Make it so ghost wolf is reduction to slow effects (relentless but for slow percentage)
Ele - Slightly too tanky with primal elementalist build, two walls is over the top.
Enhance - Needs to be reworked
mechanically on DMG rotation bring totem weaving back if required. Lava lash needs to matter (flametongue stacks?)
Restoration - Earthen totem slight nerf, make healing tide and healing stream stronger but killable, remove healing rain magic Dispel honor talent not healthy for game.
Totem placement and totems in general should matter it adds class fantasy and flavour.
Mage
Arcane -three is to many blinks, let them have two with shimmer effect (only arcane)
Fire - see OP statements.
Frost - Happy with where it is currently if running optimal traits in terms of damage. Bring back deep freeze for kill target only. Require that poly cannot be used on the deep freeze target for x amount of time after deep used. Give them one blink or one blink stun removal with second blink mobility only. (No shimmer).
Positioning properly on mage used to mean something the same way hunters had to get fancy to land traps.
Hunter: Bring back “eatable” traps, old trap launcher for frost trap.
Survival looks to be in a good place, in some metas the utility might be a little much. Undispellable root/diamond ice in twos may need to be looked at.
Mm - see below (wrath chimera? Diff stings change effect)
Trap launcher/(wrath)chimera or arcane shot prclo
BM - Bring back pet utility like turtle intervene (wrath) something that adds complexity to the pet control aspect of the kit without making it monkey stun level broken.
Monk - Make portal place you on the same plain (level). If portal on second level of blades edge make it so monk ports directly below it (z axis).
Windwalker - DMG needs to be toned down.
Bring back brew stacks (mop tigerseye) for hybrid tax/high armor target disables.
Mistweaver - 55s cuccoon needs to be nerfed back to previous. Give this class a brew that can be used before a cc lands i.e makes poly 6s if used prior to poly landing. This could assist them in breaking out of the cleave healer niche and give comp diversity. Reduce overall mobility slightly so melee can actually connect on them ( or give warrior/dk a crushing blow or sobering stance passive effect so that they can actually hit/reduce rolls from a monk) this class has a real rock paper scissors effect versus specific classes but struggles versus cc heavy comps.
Arms - Fine, other specs need to be changed in order for this class to improve. (Monk mobility/mage shimmer) they could add a cc reduction overtime to the spec to make it so the longer your in cc you obtain a damage buff or a proc.
Fury - needs to be slowable at some point in a match make slows gradually Dr longer due to anger if you must. With a refresh timer on it and passive troll racial.
Prot - I don’t believe in tanks in pvp but if this is to be a thing make it a stunlock spec that is killable. Its niche should be disruption and NOT a tanky DMG spec.
Paladin:
Ret: I find ret mechanically has had issues due to it’s more simplistic rotation and mechanically low mobility outside of charger. It’s niche is always with a hunter. I would like to see off healing and DMG for this class be a choice, nerf it’s on demand burst buff the static DMG but require it to have a builder or debuff on target. Hybrid tax should exist as well as healing ability. Instead of stun/silence removal maybe make it apply a stun cc duration reduction if applied before stun, make it remove silence. This would add to the skill of the effect.
Hpal - Throughput is strong, Mana needs to be nerfed in line with other healers slightly. Thank you for nerfing sac to one stack was a good change.
Rogue:
Assassination - Fan of knives build can be too strong when teams are stacked this is largely due to slow being too strong. Otherwise seems decent after recent changes.
Subtley - buff DMG slightly but ensure it remains the control rogue spec, it shouldnt have too high of DMG but more than it does currently.
Combat - range stun/kick range need to be reduced slightly. Blind on a 1 min 30 CD might be over the top if this becomes t1 again.
Druid:
Balance Starfall needs a little bit of a DMG buff in instanced pvp. Otherwise currently struggling due to destro meta.
Feral: Make Savage roar honor talent to give a bleed based spec option. Look to buff the damage when paired with this option to ensure hybrid tax but also provide real damage to the class if used properly. Feral cyclone being kicked should punt the feral in the air for one(or .5) second to provide counterplay.
-Restoration - reduce Soul of Forest regrowth throughout scaling with mastery. It needs to be a strong option but reduce it enough to make it a more competitive tier.
Spring blossoms in pvp needs a throughput nerf when stacked with full hots, the Mana cost should be reduced to compensate.
Lifebloom bloom effect when purged needs to be buffed as this is our sole purge protection. Currently it is presenting to be too weak in this regard since shaman/priest purge Mana buff in terms of game health.
Thank you for fixing utility Mana cost.
Boomkin affinity should not allow nourish to be casted inside it.
Feral affinity - all healer offensive builds should not be able to hit harder than a DPS when bursting. Way of crane/melee wings seem to have been nerfed properly previously. Fero bite with master shapeshifter can hit too high and numbers may need to be tuned.
Demon Hunter:
Remove Mana burn from this class the Mana nerfs were enough to begin with.
Priest:
Disc needs Mana change reduced
Personal opinion: Dark arc is great for disc but bad for game balance health when used on partners. I.e legion mm jungle.
Give disc premonition baseline
Power infusion? Reduced spell Mana cost CD.
Shadow - numbers tuning, fade CD might be to strong.
Random idea: Void tendrils were an interesting trade before.
MC should be 6s and not 8 as it is a range fear option.
Deathknight:
Diseases should not sit healers up when drinking if healer is behind pilar or a certain amount of yards away.
Death coil needs some love, as long as pets DMG is nerfed to compensate.
- Things to fix in the future:
- Fix mm hunter mechanically in pvp (give it a build that can utilize a ranger type kit that can kite) rapid fire is a newt concept but give them a focus dump that is instant and does decent burst but less than casted.
- Come out with rework for affliction that was promised.
- Certain class specific azerites should become passive once system removed. Ex: swiftmend hot, latent poison, shadow apps, tunnel of ice. Honor talents should feel like a choice and not a requirement.
Bring role defining abilities back to being passive i.e dk spellsteal, resto druid cyclone (magic) (make honor talent make it current undispellable version or 5yrd increase)
