There are many fights in which as either caster or melee this is possible. After reading EJ and seeing many unholy DK's pulling over 6k dps in heroics i ran on my tank (some were even undergeared) i was thinking that something like a DK with a 1 button rotation like they can have would be great for such a thing(as they nolonger use SS glyph), as well as things like arcane mages. I don't see many instances where having multiple shaman would be useful for such a thing as their DPS is quite low comparably to other such classes that can have 1 button type DPS rotations (not able to break 7k).

I watched my roomate do ICC the other day and it doesn't seem like any of the first 7 bosses would truely require much effort to tripple DPS as a boxer with the exception of possibly gunship. The fights in ToC would not require much work either other than the third boss, but if you are doing strictly 25 man content with them 3 of say 12 DPS not being able to CC or whatever would not kill the raid especially as a caster and in some cases if you were running a tripple DPS group like say... Mage, Warlock and Shaman you would have cooldowns that do not share diminishing returns so you could also single handedly keep a mob CC'd with sheep and fear without needing to rely on others to do so (for example 10 man version champion fight)

In my opinion something along the lines of

3x dk or 3x rogue would be most effective with teams like i said before of mage/lock/shaman or tripple mage or tripple lock would come in shortly after that. I don't see paladins pulling high end DPS as their priority rotation would need to be managed for three separate characters, so if you were to somehow manage to do this effectively then it could work. The major problem i see with Ret is that the 2 piece tier 10 bonus is too good to pass up but using it efficiently on three separate toons would be cumbersome.

So my question to you is. What do you all feel would be the most efficient at being a good raid member (high dps) for raiding new content?

Please keep in mind that i am assuming that people attempting to do this have common sense, meaning things like being able to either visually see or set up audio que configurations for when you get debuffs such as being targeted for putricide's brown slime kite to either be able to PiP switch and change focus and run away or take actions based on similar situations.
