The Warhammer launch last night was great in my experience.

Only a 200MB patch on retail and it was a go. I have to say the RvR was fun even for a lvl 2 Zealot. At least my heals could help keep lvl 10 tanks alive while moshing in the fray.

Warhammer is my WoW killer; no more multiboxing for me (not that you can't do it I just don want to).
