Part of the issue in Classic is the "Hybrid Tax" where Shaman, Druids, & Paladins have major issues in multiple roles.
Much of the Hybrid Tax was removed in TBC and it was adjusted further in WoTLK (maybe too far in some roles)... They reason they can stack well is because they become good at both damage and healing and are fairly tanky (multiple roles) and uniquely have some Artificial Intelligence in their tool box that can really help multi-boxers (targeting by Chain Heals, Chain Lightning, Tremor Totem, etc)...
Mages are still good in TBC but their unlimited AoE is gone and they cannot pump out heals like Shaman and aren't in mail with a shield. Their strengths include avoidance which is somewhat based on movement which is not a typical playstyle for many boxers. They still have great CC and damage and will be good but I think Tank3MP will be better than 4MP for most people in ClassicTBC (and Paladin4Shaman will be better than either of those).
