Those DayZ and Wasteland player's don't give a **** about this game, this game to them is just placeholders until CoD whatever or the DayZ standalone comes out. Don't let them try to change it, they never stick around anyway.
BIS, I'm not making any assumptions or anything, I don't know how you respond to what some people want to change in the series, I am just player who's concerned. So far ArmA III looks near-perfect.
Here's a suggestion for grenades, G pulls out your grenade, hold left-mouse button to pull it back and release left-mouse to throw it, just like Arma II but without using the Action Menu. Many of us think the current grenade system is a downgrade from ArmA II.
