basically i have 1 loom for a rogue but im not sure which to roll which are better at 85 which are fun also?

Rogues are honestly not much good for raiding from what I've seen but fantastic for PvP. They can be very fun to play but are all about burst DPS.

Hunters, on the other hand, have some pretty fun and unique mechanics. They are very flexible and can be one of the best raiding RDPS units, with the bonus of melee damage from pets. My guild leader is currently leveling a hunter and he says it's one of the most fun toons he's rolled.

That said, both share a weakness of lacking an AoE attack for many levels. This can make solo questing difficult so one of your best bets is to partner up with a mage if rogue or feral druid if hunter... or just run dungeons.

I love my rogue and my hunter. Both are fun to play. You should choose depending on your play style. A rogue is melee, you're going to be in direct contact with mobs all the time. Hunter is ranged DPS, you should not have a mob close enough to hit you.

Also with the rogue you get to pick pockets. This will keep you supplied in healing potions and little extra cash.
