Bronzebeard is the business. I haven't heard a peep of grief about multiboxing from 1-79 and in fact I've made a lot of friends just from chatting.

It's a nice, cool server that's been around a long time. You wouldn't want to roll Horde here (there ARE no Horde) but the battlegroup was good at 70 - haven't hit BGs since then so couldn't say what 80 is like for PVP.
