Well, there’s this thread where I talk about how the fact that Valkyrie being a long, kit enhancing ult makes it incredibly difficult to make interesting and why making it’s main draw be what is essentially an aura is bad.
Then there’s this one where I talk about how Mercy can’t do more than just heal at any given moment, is the only healer who hasn’t got a way to give more sustain temporarily, but still has very low HPs numbers. Also I talk about how the downside that Resurrect currently has not fitting her kit and Resurrect being more impactful than Valkyrie (can you name another hero who’s E is more impactful than their Q?). Then finally several other problems I have with Valkyrie.
I had another thread that talked about how both Mass Resurrect and Valkyrie are fatally flawed… but I think it got deleted because someone necro’d it. That’s unfortunate. (Edit: Found it Oh hey, you’re the last poster in that one. Huh.) Anyway, Valkyrie’s fatal flaw is that it is in the “ultimate” slot. The definition of the word means the best of that thing. Naturally people expect things labeled as ultimate to be ultimate and Valkyrie is not the best at anything it attempts to do.
This rework here is my latest rework attempt. I have others if you want to see them.
As for the balance vs fun thing… I doubt either of us will convince the other of our point of view so I’m just going to drop it.
