The lack of support for alts in this game really irks me. I know its better to have one character because cross class skills, you can't mail things between characters, etc.

Some of us just like having alts for a change of looks every so often, or to replay the story, or because we're RP'ers. Some have friends on other servers that we want to play with and since there's no cross-server friend list like Blizzard's Battletag and (afaik) no word on when we'll get something like that, we have no choice but to have alts.

For those of us that do have alts for whatever reason, it would be nice to have some things cross over, like UI settings and achievements. Mounts/minions/titles are a small maybe, things like unlocked glamour and dyeing are a huge maybe but I don't see why not.
