My Druid used to be on Horde Blackrock. Never again. Augh. I'm pretty sure I'd pin it as the worst server community wise that I've played on. >_> Mm. Methinks when I start up at Cata, once I've got my share of alt-levelling/raiding/dungeoneering, I might try the challenge of Cho'gall Alliance. I've always enjoyed levelling on outnumbered sides. The opposite side is usually horrible at PvP. On Kel'Thuzad, it's mostly alliance populated, and there's always raids of 5 or so odd people in full wrathful wallhacking up on the hut in the entrance of Org and killing flagged players. It gets annoying fast if you're flagged, and rarely can you get a group of enough people to get them out... Enjoy leveling though, if you're good at PvP, you should rack up quite a few HKs getting 80, and it's nice forcing people out of your grinding spots.
