Wanna see some new things in supply crates in Mutation modes

The supply crate in MM/HM/HMX is too dull. There is only so much you can get like M60-A, Mutation Grenade, MP5 for some reason..., Thompson and other blahs. We may add some buff effects to the player inside the supply crate for example:
-10%movement speed increase for 20 seconds
-25%more damage to mutants for 45 seconds
-Unlimited Grenades for 5 seconds
-Maximum ammo increase by 10 rounds (rifle), 5 rounds (sniper), 8 rounds (pistols), 3 rounds (shotguns), 20 rounds (MGs), 30 rounds (SMGs) for entire game
-Knife damage increase by 100% for 30 seconds
-10 EXP bonus
-20 GP bonus
-one more grenade slot for the next round
-All mercenaries immediately gain 5% increase on mutant damage for entire round
-One magazine ammo replenished (:P)
-1 ZP bonus

So some players may go pick the supply boxes. Some players got good guns so they don't use the supply crates, then what is the point of them? Please consider my suggestion!
