The ammo cache abuse was annoying, but don't hang me for saying this but I found the flash bangs useful in sticky situations. Just annoying when you die and your watching someone who got flashed and you become flashed when respawned. Also how even though your blinded and get hit by another FG the effects stay on even longer.
There is no better way to defeat your enemies but to slice and dice em right Link?...oopz forgot you can't speak. Well I guess a simple head nod is sufficed.
