They are going to get continuously worse damage as a result of this decision. It is an inevitability, and we've already seen it happen with Tassadar. This is the consequence of this design choice.
The design behind the old Archon was terrible. He was a bad hero that turned into a god every 2 minutes for exactly 12 seconds. Is that your idea of "damage"? It shouldn't be, because that's horrific design and not fun. If you're mad about his damage, look at his 13 and 16 talents. Blizzard's change to Archon was great. Tass had huge flaws. They solved one of them.
Now they need to look at his 13 and 16 tiers. If they'd put some meaningful talents on those tiers to further enhance each spec instead of Tass players being forced into E talents, things would be a lot better.
Personally I wish they'd just delete Prescience from the game. Imagine that hero without Prescience/Dimensional Warp and think about how bad he would be without them -- the rest of the talents on those tiers are total trash.
It is player stupidity. They were in the game for close to two years as Assassin/Heal hybrids without an issue. If you played them, it was blatantly obvious that they're not supposed to be healing a team up- no healing Ult being a giant clue alongside their marginal healing output. The issue was the QM matchmaker, and they chose to address it by warping heroes around the matchmaker instead of just fixing the damn mathchmaker.
That's a bad argument because it disregards every single new player since that patch.
Having a Tyrande solo heal shouldn't be a normal thing, it should mean you're a hyper-aggressive comp making a very sizable tradeoff in sustainability for more DPS, the calculus of which has been massively altered w/ the changes to Tass/Ty.
except that's exactly what happens right now when they solo heal. Their numbers still do not compete with Uther/Malf/Rehgar/etc. Karazhim is the exact same thing as Tyrande design-wise yet I don't see you complaining about him. The only difference is that Seven-Sided is actually good whereas Starfall currently isn't -- but I expect them to fix that.
So are you saying Monk solo heal shouldn't be a thing either? I really don't understand.
I hate that Tassadar's ability to be agressive on DPS got hit in order to make this happen. I hate everything about the thought process that led to that decision being made- the logic is back-asswards and it leads to a game with less diversity in hero archetypes, not more.
It got "hit" by fixing the stupidest, most broken Heroic in the game. Tassadar is in a much better place for it. Again, if you want Tassadar damage spec to be a thing, ask them to re-work his 13 and 16 tiers instead of complaining about the recent changes to Archon.
