I don't understand.

Everyone plays differently!

If you feel that you are lvl'n up too quickly then stop lvl'n up that way, slow down and enjoy the game. If you need/want to get a few lvls really quick then there are ways to lvl quickly, but if you want to go slower and enjoy your experiences in the game then there are ways to do that too.

It is possible to lvl fast and possible to lvl slow!!!!! The best of both worlds!! Why complain?!?!

Stop concerning yourself about everyone else, not everyone plays the same way as you, not everyone enjoys the game in the same way, play how YOU want to play!!!
