Classics do numbers right. Retail inflated too much to the point where it needed to squish multiple times.
The stat squish in retail MADE OUR CHARACTERS WEAKER. My clear speed of cata raids in Legion went from 15 minutes in firelands to 45 minutes making mount farming feel gross.
In classic getting upgrades feels better because there are less random procs going on with your damage. As a frost mage there’s frostbolt icelance and that’s it. You don’t have ice shards flying in or trinket procs that scale from spellpower or set bonuses that also do things or your artifact power item of the expansion having some chance on hit effect. It just creates a cluster mess of numbers.
In vanilla classic mages only have frostbolt but it felt more interesting to get upgrades. More mana meant you could frostbolt for longer. There was a game of using mana gems and pots just right to last the full fight. When your frostbolt moves up from 1000 to 1100 to 1200 to 1300 it feels good. There is a visual of your power actually growing which is great to see.
Raiding was better in classic too. It was more casual based and didn’t take itself too seriously. I think this is a better approach than trying to make people die 20 times on each boss in a slog feast. It’s nice to have 1 raid that everyone walks into or doesn’t walk into. Not having LFR mythic heroic flex whatever.
Normal raids only cause people to get more addicted to the game, LFR causes people to play whenever they like and quit whenever they like. It’s why cata started draining subs.
Also by Wod the difference between heroic normal and LFR gear was so little I didn’t really care. Just getting full iL700 was good enough.
In classic you wanted the best gear because it would improve your daily farming speed and your low level dungeon clear speed. It could also improve your pvp set or just make dungeons fly by faster. The difference between a full naxx25 gear player and a greens and blues iL190 player is pretty big.
In retail there isn’t really a +100% more damage if you collect all the raid tier gear instead of settling for blues and greens. In retail you can get full LFR gear and get +90% more damage and miss out on 10% from not getting normal/heroic/mythic. But you can still farm old raids really fast in full LFR gear.
Pvp is more unbalanced which means more fun. Balanced pvp is never fun, it means all the classes have answers to all the other classes. In wrath classic each class has a weakness and a strength. Arcane mage for example is the weakest 1v1 class but the strongest pvp dps glass cannon.
There’s also the fact you can use pve epics and legendaries to gain a huge advantage. Pve gear has more damage than pvp gear but you don’t get resilience making you squishier. Because pve gear would have 2 secondary stats usually like crit and haste and pvp gear is just crit and resilience. Also pve gear set bonuses from tier sets could be utilized as well if the bonus is strong enough.
Retail removed just about every RPG element that made wow feel like a video game version of dungeons and dragons. Hunters don’t need ammo. Quest are conveniently designed to be done in 5 minutes always. Warlock pets don’t need special books. Talent trees are just boring spells you choose. Character customization is very bland.
In wrath classic you have so much to customize. You can choose glyphs, talents, gear for pvp do i want 10% resilience or 15%, if i take 10% i can do this much more damage ect. It’s a min/maxers dream.
