I want to suggest the Character storing service aka the Barracks for Lordaeron (not only for Icecrown and to the same conditions regarding the contributor status of the account).
My main reason is that I have too many high leveled characters. I would love to be able to participate in events on that account (with the required level 1 char) and level a 11th and more character.
They don't, I checked after I saw the suggestion. Could be they're saving up space or there's little or no need to do it since people rarely hit 10 characters on Lordaeron.
Would be cool to see it though. Kinda weird having it only on one realm.
This feature is called Barracks. Any players that reach the account limit and have a forced addition of characters to their account (usually due to realm transfers), will have this system available at their disposal, regardless of their account status.
u cant be forced to have more than the limit in lordaeron
donors will use outside that too some day
