It's a good way to save that garbage weapon line for good and at all levels, and requires only fiddling with a few database entries so Michi could accomplish it with current staff levels. Plus its like all RP and ****, grenades only need to be aimed in the general direction of things you want to die etc.
In fact lets have them be 200% attack skill grenade instead of 50% defense skill duck, just so engineers can post screenshots with 5k AR and land champion perks.
