I leveled a paladin into t3 as my sixth. When arcana released I realized that I had no way of expanding my roster. With paladin being my lowest invested character and requiring a completely different set of engravings from any others, he was deleted. I really believe the only true solution is the same as all games today. GIT GUD.
I really did not know that character extentions were one of the only things in the game locked behind swiping. Truely is sad because there are so many classes I would love to play but I have no way of doing so without playing on more than 1 server.
