i ve played insurgency sandstorm for 8 hours since the launch of beta 2 and the only thing that really bothered me is the amount of damage the melee weapons do. it is almost impossible to kill someone with a melee weapon in the current state of the game. the new ammo management system that was introduced in sandstorm amplifies the need of a strong melee weapon, however there isnt one which i find quite annoying. Basically, look into buffing melee weapons.
