Add me to the list of people saying the best way to upgrade for Age of Conan is to cancel your account. I had a good time in the beginning, got to 80 fairly quickly, then found nothing at all to do but grind the same mobs/dungeons or run around in pointless gank squads. Unfortunately, the game is just too screwed up and totally unbalanced. It's a shame, really; I was pretty optimistic about this and thought they would have learned their lesson from AO, but it's almost an exact repeat of the AO release without the server instability.
AoC had amazing potential, but they've managed to squander it completely. They had a great, highly interactive and innovative melee system that gets trumped by casters who can push the same two buttons over and over to kill you. In a lot of situations, caster vs. melee fights just end up feeling like that scene in the first Indiana Jones movie where the guy pulls out the sword with a flourish, then Indy just shoots him. I've been following patch notes occasionally and it sounds like they've fixed some of these issues while lots of others have cropped up. And if you're Waiting on Warhammer ... from someone who's played beta: don't get your hopes up.
On the plus side, there's really an incredible amount of fun to be had going back and playing some of the classics. I recently dug up the Fallout series and I'm playing through that with the high-resolution patches at 1680x1050. Looks and works great, and man are they fantastic games. Re-playing the Baldur's Gate series with the high-res patches next, too. Should keep me occupied for quite a while.
