The EXP Curve

Because that great achievement now is lost. Everyone's able to get to 192, so there's no achievement in it.

Nevertheless, everyone's talking about getting to 200 as if it is a big deal nowadays. It is not. There are 371 people who are already at that level. It was amazing when FangBlade did it, but now it's more of a boredom. It's nothing special.

It's not lost. It's still there. You leveled on the old curve. You loose no stats on the new one, you deal the same damage...

How about training only on zombie maps? Because newer players have the advantage of training on newer areas. Someone leveling to 140 only on zombies was a great achievement, too, but I see nobody complain about how that's lost.

EDIT: Isaac, or whatever name you have below that IGN, that's the best post to define all this.
