I miss them sticking to anything. I have had them bounce off walls and pve targets and of course PvP. It is one reason I don't gunslinger as much, no sticky grenade. I enjoyed sticking since I first found them in halo. I enjoyed sticking a knight or cabal or one of the 2 major minotaurs on venus.
It won't stick to bosses.....someone please, not satire, allow it to stick again
Tripmines were never complained about, don't know why nerfed them. On the other hand, the huge buff to Golden Gun's damage in April Update was well needed.
