damnit, why on earth would you hate that class? it's epic!
But fine then what woudl you think a good class woudl be for a shy Aasimar?
My personal suggestion would be either a cleric or an oracle. Probably more leaning towards the oracle, since clerics tend to have a bit more public profile.
Thought that comes to mind for my character is maybe a bit weird, but an elf half-fiend. Don't remember the name of them, but there was a race like that in Forgotten Realms as well that I really like. I imagine that'd also fit the bill of something people wouldn't want around and would gladly throw away to never be seen again.
