Thanks for the tip. just one question, how do you get the 10 classes ? i've tried but it says that i can't have more than 2 classes.
That is indeed the standard You can increase the maximum without any cost from 2 to 3 when your main and subclass reach level 20.
In the city of Varanas, Silverspring zone, there is an NPC in the Eye of Wisdom that can increase your maximum classes from 2 to 3 for free, from there on you will need to buy class expansion tickets from the item shop, as well as race changes in orde to retrieve the classes from other races (champion + warlock = dwarf specific, priest + knight = human specific, warden + druid = elf specific)
Thanks, that has been very helpfull. i'm progressing with my sub class rigth now as soon as i get to lvl 20 i'll try that :).
