It won't. At least on LAN games it won't. My friends and I also play at TBun Aman Suria and we all share the same profile, all with the same cd-key. No problems so far.

As for the game mode I prefer domination. TDM not so fun especially when there are more than 10 in a team. Everyone tend to bunch up and always got killed right after spawning. Domination mode need more teamwork, and allows more strategy in playing.

Haha why not! The only reason we are using the same cd-key is because its easier to remember just one. BTW I've seen a few lvl55, but none called "s*hai". Most "s*hai" I saw are quite noob, regardless of their level.

Perhaps you guys misunderstood what I said, when I say sharing profile doesn't mean when I level up I pass my account to my friend, and when he plays and level he passes it back to me. I mean we just use the same cd-key, each with our individual names and classes.

I'm still far from lvl55 (34 or 35) I don't play that much in CCs, and I don't play at home. Every level of mine I earned it myself. So I really don't see any problem with that. I actually have the level 55 account, but I don't use it, just because I feel it defeats the purpose. It's more fun earning XP and unlocking perks and weapons when playing.

You can say that, but everytime we play, we play together. And some of us tend to lose things easily. We figured this would be easier for us, at least now it doesnt matter if someone forgot his key.
Anyway you play at TBun often? Don't know you've seen, but we are the bunch of dudes who refuses to play TDM everytime and host the domination maps.
