I know how you feel. I hit 58 on my Epic Pally pre-velious and haven't really done much with her since then.
Have you done the Divine Might spell quest (
http://wiki.project1999.com/The_Bone...k_Lightforge)? It's pretty fun and the only semi-challenging part is the one from Kedge in Phinny's room. But any pet class can pull off the seahorses for you to swim down there.
I love my Pally but I've moved on and I'm leveling alts. I now have 5 50+ toons all with their epics which is kinda cool.
If you do move onto alts I'd recommend hitting 59 first for that 90% rez. Having a rezbot is handy when leveling alts even if it is only a 90%.
