4 mages, all fire, all frost, or a mix?

[Apatheist]

So I think I'll go with frost for the control but I got to wondering...would a boss a few levels below me, but still able to give xp, be able to be nuked down a good bit with a scorch pyroblast combo coming from all 4 mages? While the control part of frost is great for the trash it doesn't work so well on the bosses.

And I was thinking of using the pally to go shockadin with some extra defence from the prot tree. More so to buy some time for the mages to DPS before I lose aggro and they face tank. More of a DPS race against the boss than a proper tank setup. After I looked at some of Xzin's stuff priest is looking interesting as well, but either way wouldn't have a proper tank.

Generally I would think the best way to approach a boss would be to spread your mages out, pop all cooldowns and then open with your biggest, slowest casting spell. Then spam fireball or frostbolt. Ice block and the boss will run to another character. Repeat. As frost you get 2 ice blocks with cold snap plus BoP with the paladin. Some bosses are even able to be slowed so your frostbolt will do work.

At least, that's how I'd try to work it in theory. I've never made an all mage team. Bit too squishy for my taste.

Once you get a decent amount of spell damage I suppose you could try an arcane/fire build with PoM and pyroblast and see if 8 pyros plus a fireblast is enough damage to kill a boss.

800ish base damage
~300ish spell/fire damage
10% damage from talents
30% damage from AP

That's around 13000 with no crits from pyro and another 2800ish from fire blast. So like 15000 damage all up assuming average fire resist. Emperor Thaurissan, last boss in BRD, has around 26,649 HP.

I'm thinking using frost and bouncing the boss around with invulns would be more viable. Either way seems like, bosses with add spawns or other mechanics would give you trouble.

I remember seeing videos of Xzin grinding PvP ranks but I don't think I ever saw him do dungeons. Are his videos still available somewhere? Wouldn't mind watching a few. I'd be curious to see how he managed a boss like Kromcrush or Scholomance trash with all those silences and knockbacks without a tank.
