These grenades known as "sticky grenades" are causing people including myself some anger. A simple fix to this is no tracking what so ever. Still one to kill but just takes some more skill to stick. To counter this you could make it so sticky grenades stick and don't fall off. Or even up the blast radius a little bit

How about not. Back when trip mines were able to stick, the had no magnitude. It was insanely difficult to get a kill. There will be absolutely no point in using them if you target can move and in other direction.
