True with CTF, you do grab the attention of someone destroying the mines around the flag. You should be on my team, I'm the idiot who runs into the mines and takes the fall for the team. (Ill be a wingman, but no fat chicks)
About the M4 and Mk, I discovered that sometimes putting a silencer on (if you can) will improve accuracy, but NOT ALWAYS. REGARDLESS of what the stats are on the weapon or mod. And if your accurate with two or three rounds, you'll kill them before they have time to re-aim. That's why I like the G3 over the Ak47, unless I have the silencer(the level 3 silencer which got me reset) on the AK for the recoil. So before you buy an extra clip for a gun, think about a silencer instead. Less bullets wasted. (Yes, I did notice this when I had a few accounts to play with and test out the gear)
