Thought it would be a good idea to have a thread dedicated to all the comments etc for the patch rather than a bunch of spec/role specific threads. Maybe I'm wrong, shrug.
But I tried all three trees and here's the short and curlies:
Blood: The rune refresh-proc thing was disorienting at first but could add some fun to tanking rather than a static rotation. Otherwise wasn't really all that different than before. Felt solid. There several details I need to look into, but I need to run a heroic before making any determinations.
Frost: Bugged; rune cooldown a mess and Howling had no cooldown or target limit. Fun (in being OP) but needs to be fixed before I can really give it a test run.
Unholy: O. M. G. That's fun. Running in Unholy presence with Festering Strike and Das Uber Ghoul is a total blast. I'm really jazzed by how tight the tree is now even though I serious miss Corpse Explosion. Yes I know it was a useless talent point for the most part but it was just pure evil fun to blow up bodies. Overall the numbers looked good, not great but I'm guessing that's more to do with operator error than the mechanics.
