I'll tell you why I play BM. It basically boils down to one thing:
Pets. I know all Hunters have pets but only BM's have
Pets. As a BM, your pet is your friend, your companion, someone you can always count on to have your back, unlike Survival and Marksmen where your pet is only there too do as much damage as possible before dying.
I like the fact that, as BM, if your pet dies, it actually matters. If a BM's pet dies, they
should lose 40-50% of their DPS. Because, in my humble opinion, Hunters are all 'bout the pets. Without a pet, we are worse than useless. But with one, our power reaches heights previously unimagined...
I don't know about other BM's but when any of
my pets die, I feel an almost physical pain, which means I immediately drop whatever I'm doing and ress him. Doesn't matter if I'm supposed to be trapping something, or it's during a boss fight, he's
my pet, my friend. That's all there is to it. Any Hunter that says otherwise is, in my opinion, just a mail-wearing mage.
