The easy way would simply to change the char name color since currently it's only blue/red for the PvP flag and Green for the team...
But honestly, even if there are grow spells, even if we spend most of our time shrinked... the size thing is cool haha
Titles are tough btw since you can't find that many way to say the same thing :/ the current class name are allready odd enough :P But I definitly like the idea of having a little something that shows at first sight what your level of AAs is.
