PvP characters are going to be alot more useful now that you can customize every aspect of them. The underlying purpose of RP characters is go on treasure hunts for skills and runes. And with only 4 slots this is going to mean that deleting your characters will be a fairly routine ordeal. Supposedly the skills and runes that characters had available to them will be saved to your account. But what about the rank/fame they accumulated? It would make more sense to make rank/fame tied to your account rather than to a single character.
For example, suppose that you finally found a rune you've been hunting for months. Your main PvP character has over 200 fame points and could really use this rune, but in order to put it in their armor you have to delete your character and recreate them with the rune, but you just lost all that fame to simply modify your character.
Wouldn't it make more sense to use the fame/rank system as a symbol of a player's success rather than a symbol of an individual character's success? So if you win a match all your characters in your account gain fame, instead of just 1.

And those sticks, although it's a head with tusks in the first few ranks, do have that pretty light gravitating around it...
