Just found this. I thoroughly appreciate all the devs do to keep this game alive, and in no way empathize with the rage quit. But the OP is spot on with the nerfs. I have several toons that I'm no longer interested in playing now, due to Adaptive. Seeds, Carrion, and Rad Therapy changes have just made the builds boring and uninteresting. These weren't by any stretch my go-to toons for feeling uber, either. They were just good and fun, and now they aren't.
Makes me a little sad, but there are plenty of other toons to play. Just really question the wisdom of nerfing something so that it isn't fun anymore, esp when it was far from OP. And yes, I thoroughly read the dev notes and tried to play the toons, so please don't come at me just for being disappointed.
