The EXP Curve

Back in '05 a level 70 would make 10% an hour at Zombies; a level 160 should not be making 16% an hour on 2x.

Why not? It shouldnt take more than 20 hours for any level, even from lv 199-200.

edit: I'd be more inclined to play if the slowest exp I got was 5% an hour. Instead of taking 10 years to get one char to lv 200, I could get all 12 classes, plus-some and I would probably be more inclined to spend more hours as there would be variety and things would be much much more fun.
