You know, I fail to subscribe to any mechanism for measuring balance where STSF warrior with 100 kills is overpowered but bash spec flurry giant has 300 kills and isn't.

Its not that there aren't things that I feel are overpowered (instant kill things for instance), which may not correlate to absurdedly high kill count. Its just that "tanking very well" isn't one of those things. I'm also unconvinced that I couldn't cream STSF builds with any one of a dozen combinations ranging from conjurers to bards to paladins to etc. The only thing I wouldn't want to fight one with is probably orc. Even a flurry spec should kick their tale if they don't have damage reduction.
