In PvE the performance is quite similar, MM has better AoE and burst, but relies more on being stationary. BM is very mobile, no hardcasts.
In PvP? Play what you like, BM requires way more micromanaging of the pets if you wanna climb. The lack of “burst” compared to MM makes it require more setup to kill something.
I like both.
if they do class balances once a week now days that meen when they remove doubel tap notice how badly dps hunters doing it can be a easly 10-30% damage buff on abilties in 1 week
