Your biggest fault.

[ohsosharp]

Whats your biggest fault on the battlefield?
mine shooting without aiming hence my appalling kdr.

[Wizrdwarts]

Occasionally ignoring squad leader orders, even I was the one begging for him to put one down.

[Basil.]

Going rambo

[Twizzz]

Going for the easy body shot, rather than aiming for the head.

[Lolyn]

Not teabagging enough knife victims.

[Mukky]

Teabagging a beauty shot for 10 sec and then getting knifed

[DesmondLocke]

Not remembering in the heat of battle what color uniform I was, and either dying by someone I thought was a friendly, or killing a teammate because I thought we were the other color and I was a little trigger happy.

[Minmaster]

my biggest weakness is probably piloting a walker. i never seem to be able to kill in those things.

When I was a noob: running past APM's where other swere crouching...

Trying to knife people where it's almost impossible, it certainly cost me 0,3 points of my K/D.

When I was a noob: running past APM's where other swere crouching...

Trying to crouch and slow walk past an apm, trusting that my teammates know how to do the same. <NOOB IDIOT RUNS BY -- BOOM!!>

[AllFoamNoBeer]

Listening to my commander.

[imported_Marche]

Making incredibly suicidal runs. I just get so focused on a target I block out all the others.

[vanilla]

Not always be fully aware of my surroundings.
Running into Grenade-Spam.
Always trying to be at the front-lines, trying to revive as many people as possible and thereby risking my own K/D to go down a lot.

Mine would be walker piloting - I do decent in the other armors save transport (rarely use that), but I just can't do crap as a walker, meh.

Eh, another big fault would be being too careful of my KDR with my moretti (Used to be 70+, now its dropped to 60ish...playing a lot more pac now). I literally HIDE from snipers whenever I can - but as a result, I know most of the spots where you can hide from snipers :P

Being too uptight about my KDR. I love the game to death, but who know's how much MORE fun I'd be having if I didn't get so torqued every time I get killed? I have a buddy who loves the game even more that I do, but doesn't give a crap about his stats and seems to get a lot more enjoyment out of it in exchange.
