This is one thing I just don't understand. One person creating a bunch of alts. Well, ok. But if they are on the same account, that one account, that one person, can only log into one character at a time, so I am not sure how creating a bunch of alts adds to any server load. Not talking about any database item load, about the server load where there are too many people trying to log in at once, OR, too many in an area alike we have here. One character, or 100 alts, that is still only one character being logged in and played at any single time.
Seems like only people who multi-box adds to any problem. Even if you have multiple accounts, and still only play one character at a time, well that is still only a single character logging in at once.
