Only thing I recall being an issue really was when you were a level or 3 to the next rank of growl, now it feels that way all the time. That's another thing, growl gets resisted like crazy, even on shit lower level.
Put me in a group, and I forget to take growl off? Shit works flawlessly.
I was reading we are using the Cata version of FD too, dunno if that rumor. I've gotten into the habit of keeping my finger away from Rclick when I hit FD, no more issues other than the occasional resist.
Switched to MM anyway, never liked BM, if my pet gonna be a cripple no point in being BM. Thunderstomp does more threat than back in the day, so I won't complain about that.
