Range Hero

It depends on what you mean by range. If you're talking about bow/gun, it'd be hunter. If you're talking about magic, probably mage. I'd assume you want to join us in the guild, so that'd be horde.

As far as hunter goes, I'd probably choose tauren over orc and troll. The reason I'd take tauren is because 5% hp boost is nifty, as well as war stomp can save you sometimes if you're in a pickle, not to mention +10 nature resistance doesn't hurt either. Orcs do have +5% pet damage and 25% stun resistance which could be nifty, so I'd put them at a second.

If you're going mage it's between troll and undead. If I had to choose between these I'd probably go with undead. Undead has a 20 second immunity to fear with a 1.5 minute cooldown, +10 shadow resistance, and 4x breath which can be nifty. Trolls get 25% spell casting increase for 20 seconds with a 2 minute cooldown, 5% damage bonus to beasts, and that's about it. The 25% isn't going to be all that noticeable, which is why I'd go with undead.

That's just my opinion, but it's ultimately up to you. As far as the builds go, I can't help you there, but I'd check http://wowvault.ign.com/ because there is a bunch of talent templates on there.
