I've been playing CoH since the Rikti attacked in Beta. Plant used to be fun for me, but never close to my best builds. Now it's not fun and still not close. It can help some teams, but is much more limited and likely to be not very useful. It's also not worth taking out for a spin because the playstyle doesn't interest me.
Of course everyone is different, which is great. But the main point that's been lost here is that nerfs suck. Plant was not ruining the game for anyone. The net effect of the nerf has been to reduce the amount of fun some players were having, which is never good.
I'm concerned about the path some of the recent moves are on. I'd much, much rather see innovation done with new sets/abilities/whatever than nerfs to existing sets, even if they are spun as improvements.
