Have to love the amount of hate inside this thread. If you don't have anything constructive to reply to this thread, why don't you go elsewhere. And constructive is not telling the op he's stupid or wasting his time doing vanilla raids. It's his choice what he does and what he finds fun in this game. He was just asking for some friendly advice and not flaming you people for your choice to do wotlk content. You might think about extending him the same courtesy.
Now on topic. If you hang out in trade and join the 80 raids for the old content you'll get gear easily. Of course you can start your own too if you know the strats, zg and molten core aren't hard to do even in a lower level group. Most common raids to be found are of course aq40 and 20 since they don't have attunements. Just collect the old hunter tiers from mc, bwl, aq40 and zul'gurub, they look nice and have decent stats. You'll see intellect itemized on some hunter gear too. I'd consider taking some leather when gearing up if it's high on agility and low on strength. Since at least in my experience I see mail gear dropping kinda seldom. Just go for the usual stuff like agility and attack power specially on rings necks and capes where you can better make your picks. If you don't mind it, getting the pvp weps on level 60 is a great way to get good weapons fast since they are equivalent of aq40 loot. You can get them with wg shard trade-ins from your main without doing any pvp on your lv 60. Good luck on gearing up
