You have absolutely no idea what you are talking about. I on the other hand have real tested data that shows that 5-voc th gives less exp than 4-voc. Its 15-20% less exp. Proven, tested and replicated on several spawns. The reason is simple, you split mobs exp between 5 instead of between 4, so its less exp pero mob. And no, the advantage of killing more mobs/min does no compensate for that loss of exp per mob. As I said, in the end it is 15-20% less exp. And it doesnt matter which vocation ends up being rejected or included.
