Best 5 man comps with a hunter?

[Apatheist]

Apatheist - I'm keen on running 2 mage/1 warlock. What are the 1-2 spells for each class to spam? Mage would be frostbolt over and over, warlock would be shadowbolt? Would you ignore DoTs with Shadowbolt?

Mage: frostbolt, arcane explosion
Warlock: shadow bolt, hellfire

You can use blizzard/rain of fire if for some reason you're unable to enter melee range. Some mobs have AE silences (the ghosts in RFD, for example.)

At low-mid levels corruption/wand will be better DPS than shadow bolt.

You can use macros to simplify:

#showtooltip
/castsequence reset=3/target Corruption, !shoot, null

#showtooltip
/script SetView(5);SetView(5)
/cast !Blizzard

. . . Or whatever the proper syntax in the current API is.
