1) The 3-target bonus on shiftless deeds talent hits only adjacent enemies, but it's difficult to take advantage of this because a tamed pet is typically in the center, with only 2 mobs on the left or right of it. So I was thinking maybe make shiftless deeds (with the lvl 20 talent) hit all 3 targets no matter what their positions are. And if there are 4 or 5 mobs have it hit a random 3?

2) Turn off auto-attack for mesmerize and enthrall. This is self-explanatory lol. It sucks hitting a mob you just mesmerized.

#1: Um.. I thought about this, but I think I'll keep it this way. Empowering this would really encroach on Shaman's specialization of slowing a lot of mobs. They are able to slow all mobs at once. Until then, I think you are stuck charming corner mobs
#2: makes sense to me. Rogue's flash powder does this.
