I agree... I think that, in the long term, equalizing the classes would be better for the game overall.
Then, one would make a character based on its "playability" or playing style... if one wants to be more tanky, healer, all about damage or more balanced like some classes we have. Like we have for most MMORPGs.
in RoK's old way, of course class's styles come into consideration, but in a major sense there's the premisses, for example, of "ninjas and slayers are better" and the 400 mil exp would just demonstrate it as "you need to pay a higher price for a better class". at the same time "cavaliers are weaker or less useful, thus its so much cheaper to level one".
I still think some classes will still be better at pvp, like ninjas or slayers like it's always been, and that might keep them as preferred. but still... there's probably room for a more balanced scenario e equalization between classes. all of the ideas brought up above for cav skills are a good example.
just my 2 cents
