Triple boxing instances at 70

Hi all!

I'm fairly new to boxing, but thanks to the wealth of information here I started triple boxing mages and find it a lot of fun.

I'm currently level 29 and I'm wondering which instances will be manageable at level 70 with 3 mages? Because of my time schedule, I often cannot play in groups and have long wondered if Blizzard will add solo content in the form of single player instances. Multiboxing has kinda given me that option whithout having to hold my breath for Blizzard. :D

I'm assuming Outlands content won't be doable, but what about pre-BC stuff?

Thanks in advance!

3 mages won't be able to do much in outlands instances without exploiting terrain like you see in those Hunter Vs World videos or decent gear and lots of CC. You can do strat/scholo with them if you're careful and spec/gear for huge DPS as most of the bosses in there can't be CC'd, and you'll probably have some trouble with the packs of mobs in dead strat. I did strat/scholo farming with my 4-mage team on the PVE server with quest blues/greens but with only 3 mages you don't have enough burst damage to kill the bosses in there before they nail one or more of your guys, which means a lot of freakin boring corpse runs.
