4-5s Fuse Nade
Most people would agree that the nades are a little OP, especially since it is impossible to avoid when well cooked. I'm thinking if the fuse is made with a variance of 1s for a time between 4-5s might make it a little more fair and realistic. This would prevent players from cooking it too long for fear that it would explode in their hands. In the real world, the fuse is meant as a safety mechanism for the thrower in case he screws up while throwing. It is really not meant to be cooked. Lastly, if there is no cover when the nade is thrown, I'm wondering if going prone could help reduce damage from the nade. This is actually taught in the army to reduce exposure to the blast.
