I'd really just like to see them add another ability to BM, lol. I loved it early on in beta, when it wasn't just spamming Kill Command.
I see that you'll occasionally use Arcane Shot, at least, which is nice. But I don't think it would hurt to add something else.
It doesn't even need to be a traditional shot--it can be another pet ability, but I'd like to feel more involved as the player.
Hell, let me shoot an arcane bolt at my pet, which causes them to do some almost-badass attack on the enemy. At least I get to hit a button and see something happen. :)
