I was under the impression that unlockable weapons in TF2 aren't "better" they're just "different" and there just to give it more variety not give older players an advantage? Usually there's a downside to the new unlockable weaopns, no? Well, if that's not the case, VALVe is doing a really bad job at keeping their multiplayer game balanced ;oWoe Is You said:Designing competitive multiplayer games works kind of different, though. In those, the skill is the reward. It's a bad idea to give someone better equipment just because they happened to have played longer. I get it in most MMOs where the environment is your enemy and the equipment also has this status but fighting against veterans who get access to all sorts of toys that you don't is just lame. It's a double whammy: you get steamrolled not only because you're worse than them but also because they have superior equipment.
As for the system, I find it incredibly unbalanced in itself. A new player could get a random weapon while an older player could play for weeks while playing as the Scout but get every other class weapon. Besides the achievment system, I'm not sure exactly what else they can do, but i'm glad they think the random system isn't good.
