Wolf starting companion - only thing it is good for end-game is a make-shift tank. The damage falls off HARD compared to other companions.
Saber tooth - great for both critical damage builds and DOT builds. Scales bleeds and can stack them very quickly with 2 AS node in its tree. One for 50% and one for
Raptor: Right now (I will update if they balance it) this is the strongest pet by far. You can build for speed, pure critical damage or DOT.
Bear: Everyone will tell you that bear is only good for tanking but that is not true at all. It has has plenty of nodes to boost it’s damage.
Scorpion: From my testing this companion doesn’t do very well as a critical based physical damage dealer and is best left for DOT builds.
So for BM’s I recommend focusing on no more than 3 companions and using both frenzy totem (op) and fury leap. Summoners main form of defense is mobility as most of your affixes to minion affixes. Fury leap can also boost minion damage.
Bear Saber tooth and Raptor for a critical-hit based build
Sabter tooth Raptor and Scorpion for DOT based builds.
