The other problem is the memory leak.

People I know that have problems with their game getting "laggy" when they switch characters from login, instead of quitting out and restarting the client, are getting the same lag by logging out and back on with the same character to enter the Hall of Heroes.

Perhaps they're on older machines than mine, because it's worse for them, but yeah, I start getting stop lag and large graphical effects start causing me problems too, where they wouldn't if I restarted the client completely.
