I think the experience increase if fine however, after level 30 the experience it takes to level should become linear. I've never been a level whore on any game. You know...the people that sit there thinking..."omg, just 8 more hours of clicker's quest and i'm gonna hit level 42!!! w00t!". And that stuff about you being godlike at level 20 ONLY applies if you play mounted. Once you get a bastard sword of any quality and a halfway decent horse (standard courser or even less) you can solo almost any group with relative ease. Largely because when mounted, the game becomes mostly about equipment and much much less dependent on character level and skills. The difference between a level 20 and a level 40 mounted character is not that much. But on foot, that is a HUGE difference. And even still, a level 50 foot character is nowhere near as effective and powerful as a level 20 mounted one (yes, i've had both). I'm not suggesting that you get more exp on foot or anything, just that level matters alot less while mounted, so foot characters and kinda getting stepped on (haha, i made funny...).
