Please don't change the strength of nades bouncing off walls, it renders years of training redundant and I think it's fine the way it is for a semirealistic game like this. Less bounce strenght off people on the other hand, thats a great idea. Might even solve the power issue, since then you can just throw the nade in their face and it will hit them. (Don't make them stick too much though, there should be a chance to escape if the timing is not great.)
Also what I always would have loved seeing, and I think suggested once before, is to make unexploded nades hitting people give them a bit of damage, like 5 or 10 on the body and 15 or 20 on the face.
