I am glad I read your post, I just started 3-boxing and thought it wasn't possible to do 5-man instance with just 3-toons (bad experience from pugs is to blame i guess). So I tried it last night and it worked better then I thought, did SM gy and lib. Sure it takes more time but then again I get all loot and I am in control, no stupid pulls or wipes. Will be fun to see how far I can go.
