Mulitple characters and leveling classes.

Could have only 2 retainers across all characters account wide. Up to 8 if you pay more.

Retainers actually are account wide. My lame alt had 7 from the time she could even use them.

@OP - making classes account-wide would be incredibly broken for raiders.

This game needs to be more alt friendly in general.

I don't even care about achievements and mounts, but being able to mail stuff to my alt and share my house with her would be nice....

Dunno why they don't just auto-add characters on the same account to each other's friendslists.

For raiders?

For raiders?

Yeah. Leveling alts is way more time-intensive than gearing them is. You'd be providing tons of ready-made alts for people that are quite willing to invest the time to gear them, then they could turn around and use them to sell content with weekly lockouts.
