What Sirrian said about the reasoning behind Valkyrie’s nerf was:
The quote about her “taking one for the team,” was about how she’s the most used troop in the game, by a very large margin. Good science says make a hypothesis, change one thing, evaluate the results, then repeat the whole process. This change is a first step in fixing that. Without changing something there is no way for the devs to positively identify why Valk is so overused. The forums are of limited use because those of us here are the vocal minority.
If it turns out that Valk was overused because she’s the blue transformer, these changes will have little effect. If Valk was overused because she was the best soul generator, these changes will have some effect (not a huge one, mostly due to the poor viability of many alternatives.)
I didn’t bother voting in the poll, because it doesn’t matter if I personally like the change or not; it does not change the fact that a change was needed, and the devs are making what they feel are the best changes based on the data available to them.
I don’t like the necromancy rework, because the trait’s relevance is even more dependent on the presence of a soul generator. I would have preferred if it had been changed to “Gain blah souls when an enemy dies.” This would have been useful on a much larger variety of teams, because it no longer needs a soul generator to be relevant.
