I am under the impression there are 4 official classes, in addition to all the different armor, weapon, and magic type trees. Correct me if I'm wrong, but they are the dragon knight, Templar, sorcerer, and... rogue (I can never remember the actual class name) archtypes? My friend at work last night was arguing that there are six classes total, with the warden being one of them.
I try to keep myself up on all the current info on ESO, and am pretty excited, but did I miss something?
Thanks,
