Hunter, Warlock and a shaman.

So, I've finally got my shaman to 70 (joining my warlock and hunter), and am starting 3 other shaman (initially) to level up together, with the warlock/hunter/daddy shaman to boost them where necessary.

I then got to thinking that I could run my 3 70's together through a lot of the dailies and on farming missions. I want to minimise the disruption to their setup as I will be playing them individually too.

I'm now in a quandry of which character to have as my main. The hunter I figure can just be an autofiring (steady shotting) fire and forget type of character.

however the sheer utility of the warlock and shaman has me in two minds.

I could respec the warlock to either demonology or a destro/demonic sacrifice hybrid, allowing me to either run with a felguard and shadowbolt like mad, or sac a succubus(for increased damage ) or felhunter for mana regen) and just shadowbolt spam.

Alternatively I could just have my shaman drop a couple of totems in a castsequence and lightning bolt spam, and have the warlock as my main.

Does anyone have any experience of a Warlock/shaman combo (With or without a third)?

If yes - how did you handle it?

This is just theory, as I havn't tried your exact group.
But, I would think it would be easier to use the Shaman as your main, then have your hunter and Warlock DPS with pets (tanking) + spells.

Depending on your cast times for the Shaman and Warlock spells, you could bind them to the same key, or even spam a single macro (different for each class).
It would probably make for easier off-healing when needed too.

I know this isn't exactly what you were looking for, but I'm interested in anyone elses input on this too. :P

I would definitely consider the Shammy as the main as he will be the one dealing with selecting who to heal, players or pets, setting down specific totems for each fight, etc. The hunter and warlock can be set to /sick pet, DoT, Autoshoot while the shammy heals, shocks, melees as necessary. It would be nice if they were all the same race too, maybe Orcs? =)
