Aman'Thul is mostly my alliance realm with a 70 Nelf Hunter, 65 Nelf rogue, 62 Draenie warrior, among others. I do have 1 Belf hunter there, about 35; which sorta ended up in my former (rogue still in it) guild. When the guild master left for 2 months without a word, and the mass exodus began (my main left also, officer though he was), another officer started a horde guild for a bunch of us to get together
I've got a 70 Orc hunter on Gnomeragan, and haven't really played him much, but a 25 troll hunter on Barthilas (which is a PvP realm). Mostly, one of the people who I played with from August last year, ended up with a bunch of real world friends rolling horde on Barthilas and formed a guild together. I created a guy over there, after he told me about it. Was familiar with the quests anyhow, having had a (then 69) orc on a dif realm.
