*oops, meant Thrash. Language ig not set to ENG, got confused
Always thought it was for 3+ targets but I regularly see other ferals use it on 1 or 2 targets, too. Not to trigger BT, mind you.
In high rated PvP there's also streamers that keep Trash up, which I don't get because it has such a high energy cost and comparatively low damage. Only scenario where that'd make sense is to prep for combustion, perhaps. Or for BT, although you always use Brutal Slash in PvP anyway so that shouldn't be the case.
