Seeing there was the specific mention of mage class changes I parked my response to most of these until they were out on the chance this thread was no longer relevant for feedback. Personally I wanted to test them out before writing anything down.
Brain freeze change - Doesn’t effect us and I don’t believe it will actually effect anybody due to how the Spell Power rune scales with frost talents and ice shards.
Overheat change - Although a debuff this has now been secured as the best rune for arcane mages as I’ll break down in describing the new balefire bolt experience.
Balefire bolt changes
Feedback
This has now completely invalidated the arcane tree for healing mages. The first thing I did was a typical arcane PvE build that took ignite and ice shards, did a few rotation checks and realized there was no reason to go into the arcane tree at all and used the full elementalist frostfire bolt build. I think we all know what happened next.
So the critical hits of balefire bolt hit for a great amount and climb with stacks of arcane blast charges. It’s almost on par with frostfire bolt spam (I won’t get into the nuances of why it’s not as good here) with it dealing more damage with arcane blast charges. It benefits from all relevant fire talents, fingers of frost charges and applies winters chill as expected.
The rotation applies almost perfectly so most group fights look like this.
Mass Regeneration (+fireblast) > Balefire Bolt (BFB) > BFB > BFB > BFB > BFB > Line 2
Mass Regeneration (+fireblast) > Arcane Blast (AB) > AB > AB > AB > BFB > Mass Regeneration (+fireblast)
Note: The reason you never use mass regeneration/regeneration after arcane blast charges have developed is because those castings cost %60 consuming the charges at the end of channelling. The temporal beacons are unaffected it’s only the channelling that benefits from arcane blast charges. This behavious will OOM yourself in an insanely quick fashion.
This so far appears to be the best short term mage DPS spec in the PTR if using combustion and removing mass regeneration from the rotation for about thirty seconds and less. I want to do more group activities with this probably for a full afternoon to refine this to be a bit more clear as longer fights will benefit from molten armor more. However it’s reinforced the healing mage role as a short term, speedrun tech only, perfect play healer.
Then I realized if I’m not going to ever use missile barrage or barrage that I might as well just slap on frostfire bolt and do some damage in downtime that doesn’t require your healing or if there’s a more efficient to mana responsive healer in the party. Your mana cost is still extremely unsustainable. You can also aid in applying scorch stacks (potentially winters chill in a stranger group dynamic)
There is a world where you do use both barrage runes and perhaps throw one or two while moving or in weird out of the usual circumstance. Alternatively using missile barrage in dungeons or low challenge while temporal beacon is up for the free healing. You can sacrifice piercing ice and get full clearcasting instead of two points into it but that doesn’t effect your heavy mana cost abilities of regeneration and mass regeneration.
So because you reap far more benefits from not touching the arcane tree you don’t get either mana bonuses in total or combat regeneration. Balefire bolt is %44-45 more costly to use than frostfire bolt and arcane mages lose sustainability as it’s always better to cast use an arcane barrage and arcane missiles with your arcane blast charges, causing it to cost far more mana.
Conclusively I’ll have to say this is a potential significant short term DPS increase for the exact same silly perfect play niche that already existed for it and homogenized mage builds. Changing hot streak to the head slot has made the head slot a role definer for mages exclusively as healers will use temporal anomoly/advanced warding, frost will use deep freeze and perhaps fire mages will use hot streak but I doubt it. This means the only flavorful difference in mages exists almost entirely out of which runes they use to support frostfire bolt or balefire bolt.
In challenging play other Mage DPS have more sustainability and better numbers, other healers have better sustainability, reactivity and utility, in pvp you won’t see changes to desired healers for the same reasons. This was objectively and improvement to arcane DPS roles but leaves the swathe of arcane healer problems unaddressed.
I’ll condense this and edit the top post to make it more focused on this phase of PTR feedback.
EDIT: Slight grammar and spelling adjustments. Also isn’t it weird the post refers to balefire bolt and not casting it ten times in thirty seconds when the minimum time for a tenth safe casts would be just after 52 seconds? I’m sure it’s just a quick joke I suppose.
EDIT2: I will respond to every meaningful post in this thread as I have previously, I just wanted to focus on this PTR change to make sure I understood and tested it as a priority.
