my BM 101 is my highest ilvl twink and i find it badass in ipvp and ok at Dungeon farming if you are the solo twink, however pets are very sluggish, Hati i find to absolutely balls, normally doesnt even move from my side until my main pet has actually attacked, if you are pulling big packs, your 3 main damaging abilities rely on having to wait for your pets to move.
That being said, i wish i had gone MM for PVE, not sure how it would have played in ipvp but BM is good for BGs.
