Plus they are other ways to level up. I find doing Leve quest in a party is a great way to gain EXP but if DRK dose start from LV1 we might be able to get a EXP boost for it.

Also LV50 ins't going to be the new end game Level anymore so people would have 10+ levels to learn it. But I can see what you mean, some players might take more then 10 levels to master it or more like get used to it.
