Hi peltz, I have seen u in bg's before
assuming that is you on <ftp bullies>
I recently tried Marks and BM at 19 (this may not translate perfectly over to 29), I personally prefer BM because
1) I get bigger numbers from it and
2) Less brainless than mm... I found myself just spamming arcane shot for dps, and I very much dislike how aimed shot is a standstill cast.
However at 29 there are a few other things in play for hunters, mm's get bursting shot @ lv 29 which for me would seal the deal right away. More cc ---> more fun. I hear there is also a bit more of a 'rotation' @ 29 for marksman.... hope this helps.
