Questing buddy classFollow

you dont really need a buddy to quest with as any spec, maybe if your new to resto but your not a squishey holy priest, 2/3 of the time before i hit outlands i was questing alone and found it quite easy and enjoyable

but what ever floats your boat, questing with a buddy not only makes it easer but more fun =D

go with a class that can keep aggro off of you if your elemental or resto, go with a healer if you enhancement

This is a good question. Being a fantastic hybrid class I don't think there is one class we couldn't gel with in a pairing, with a little thought and co-operation.

My personal favourites are casters (Mage/Priest/Lock)as they slot in easily with my Enhancement spec. If you are resto/elemental, I guess warriors/Pallies/Druids would be easier.

Rogues need the most care in my experience, they do get a bit upset when you break their fancy 'ninja moves'.

I normally find if the pairing establishes a few ground rules prior to questing then everything goes great. Any PUG that doesn't communicate is seriously hampered.

Well, having done exactly what you are talking about I'll give my choice:

And IRL friend and I first picked up World of Warcraft with every intention of playing together. I rolled an Orc Warlock, while he rolled an Orc Warrior. We leveled this way until around level 24ish. I then realized that while I (affliction) could solo much better than him. This was because his need of healing (health stones dont cut it sometimes ;D) This is when I rolled a Shammy.

Never, NEVER, did I look back. I quickly leveled my Shaman and caught up to him around level 25. We have been leveling together ever since. Me (enhancement) and my buddy (dw fury) have a blast. We burn down mobs at an alarming rate and if it gets sticky he just Defensive Stance > Taunt > Sunder, while I heal, Heal, HEAL! Haha.

Well, all that for this: I had a blast(and still do) leveling with a warrior partner. We had so much fun together. Whether it was me Ghost Wolfin' it through desolace at level 25 and watching him get torn apart (only to run back and rez him =D) or us exploring 'uncharted territory' by mountain climbing\swimming around every coast.

I say go Warrior\Shaman. I did. I never regret it.

Due to being hybrids we match up well with any other class, it's just knowing how to synergize. It also depends on what you actually want to do.

For example I leveled my first Shammy with a RL friend who was leveling a hunter, it was an awesome combination we could take down large groups with ease (even groups of elites on occasion) with the pet tanking and me alternating between dps and healing (Enh specced).
The time it really rocked was in world PvP encounters though, seriously, try getting away from a hunter shammy combo. Aspect of the cheetah and ghost wolf, as soon as he was in range he'd pop a concussion shot then I'd catch up, frost shock and we'd proceed to tear them apart.

This same friend an I are currently leveling another combo together, this time he's the shammy and I'm a prot spec Pally (now 69 and 68 respectively). Yet another awesome combo (dual hybrid combos are always good though). In this case PvP is not so open shut but PvE grinding is just insane, massive pulls, AoE tanking with him alternating between DPS and throwing me the occasional heal. Totems + Blessings = WIN.
This combo is also very effective for instances, I tank (obviously) and even though he is enhancement he's a great player and tbh a better healer than a lot of specced healers I have played with recently. Of course if we do get another healer then he can break out the DPS :-).

My basic advice, team up with a mage/lock/hunter if it's a PvP server, or a war/druid/pally if it's a PvE server.
