I just got into the beta waiting list for Champions Online. Been playing Runes of Magic for all of a week, but it's really laggy at all times of day. It feels just like WoW, with a different skin, and a bunch of core add ons already installed in the UI. So, it's nice in that respect, I was really just looking for a free WoW replacement. But it's most crippling problem is the lag, an easy fix.
Oh, and the spambots. If you play this game, immediately get out of the zone chat, or you will be flooded with shout spam. The bots haven't really started talking to people directly yet, so they're easy to avoid, but annoying still.
