EDIT: okay after reading all the grenade hate i have to give a REAL rebuttal.....

check it out.....
FIRST if your going to talk about buffing the grenade you have to talk about A REAL issue, MASS DRIVERS.
grenades cant put out half of the dps a mass driver can ,you can spam with a mass driver twice as hard, plus
you can rain g's down on people, you can only have three grenades in your inventory and it stops given them to you at certain extent so i really dont see how you can even be talking about this....

summary :
MASS DRIVER HAS BETTER ROF, RANGE, ACCURACY, NO COOK TIME, MORE ANGLES, MORE AMMO AND, ETC

GRENADES HAVE BOUNCE, HIGH DAMAGE, AND CONTROLLED COOK.....

really i thnk most of you are confused between the two. ive been spammed by g's before..... heres the kick THEY CAN ONLY THROW AS FAR AS YOU GENIUS!!!!! if he can hit you you can hit him...... SIMPLE! fixed your problem.... quit whining. swing the nerf bat at something that needs it.
...........
but if your not convinced......

second: Grenades have never been a favorite of an enemy.... they suck to have to doge and when there's a lot coming at you then it really sucks. but just because your getting killed doesn't meant you gotta ruin other peoples time. grenades are there for a reason its for strategic advantage; corners, heavies etc. and they really don't fill there roll very well at all..... the grenade spamming doesn't happen to the extent where it is a problem, especially not compared to mass driver spam as mentioned above. ....
summary::
DON'T BE A *MEOWS.

DO NOT NERF THE GRENADE PLEASE.
