I think I can count on one hand the number of times I've had someone shoot me. I've noticed that when I'm in matches where most everyone is about my level or lower (I'm level 13), people use it a lot, but when I'm put in matches with higher levels (usually when I play with GK), I don't hear it used often, if at all.
Of course, the most obnoxious thing yet is one match where someone kept using firecrackers, seemingly on recharge...
I don't hide/blend very often unless I'm waiting for it to assign me a new target and I have a couple of pursuers. Then I just go and find a group with a couple of Courtesans and wait for a moment.
