My other half actually reached the global cap the other week i didnt even know there was one but it would not let her create a character unless she deleted one on a different server (she has a lot of alts on multiple servers) this may of been a bug as i never got it confirmed. I introduced her to multibox this weekend so now she is working on filling up the other account

on a side note can anyone confirm if there is a max amount of characters you can have per account? as in total on all realms.
