What class can I make to get him right to ah? On alliance its human that is lvl 1 run to town....I need a horde this time
best would be troll\orc still a long run if you don't have some silver for fp at ratchet, bank at ratchet so if you got guild just invite and promote
Orc/troll is most likely easiest, tauren or ud if you want to be more stealthy with your banker for whatever reason.
which one can just run to (what town) to get started? Hell I don't even know what horde towns have an AH. can any of them do it at level 1 or do they have to level before they can go there?
All main cities have an AH - Thunder Bluff (Tauren) Ogrimmar (Orc/Troll) Undercity (Undead) Silvermoon City (Blood Elf) You can go to any main city at any level, some are just harder to get to because of agro, etc. Ogrimmar is the most populated, similar to Stormwind on the Alliance side. It's probably easiest to get to Silvermoon City as level 1 Blood Elf, there aren't many mobs on the way to town. And it's never populated, so you should have no issues if you're worried about lag/other people.
I botting for horde over 2 years. With my experience i can say easiest is orc/troll, faster is taur..
