Shafts. They camp, I don't really care, you wouldn't expect them to always use arcade mode and be liek: "Meh no snip, no funz. I go head to head combat wit u nub, I predict me win k." Then the shaft gets insta-killed by a Firebird.
The only turret that you could use for melee combat is basically Smoky. Like you said, I'm not going to think that a Shaft would be travelling with me to get the flag with his fat mammoth xD
Me: "Lets get the flag, no more camping. Come on dude"
Shaft: "Wait, wait, it takes time, I'll catch up."
*Freeze turns the corner*
Shaft: "AHHH KILL IT WITH ARCADE MODE FTW!" *Shoots the Freeze, ineffective*
*Freeze kills them both*
After they re-spawn:
Shaft: "I almost got him man! He was cowering with fear bro!"
Me: *Facepalm* "Actually, just go back to camping."
