I Believe it is, and it's worse than a normal hammer thumper, due to only 8 in hammer mastery, tsk tsk, and after all he said about my build, I was expecting more.
Yea, he just put alot in BM and spread everything else thin in other attributes. You only put points in BM to keep RaO Running consistently, and with 8 hammer you aren't gonna be pumping out much damage.
Why use a hammer at all then? Just for the KDs? You'd be better off with Enraged Lunge if you really want to go full BM (which may be viable if they do add better pet cotnrol, imo, as Enraged and other pet skills are pretty damn crazy mathematically)
...Not good. Never run weapon mastery below 12 unless you have a very very good reason, and never EVER run it below 11 (if you're using it for damage, that is, I understand Cripshots and such).
