Best combo for MB

[tripleboxed]

For just two characters, I don't see any point in going with a tank + healer. I would only do that if I would box a whole group.

I would highly recommend two mages, both of them identically specced Warlock / Necro for 99% of all play. In Necro you want Soul Purge and the upgraded pets. For a few things you may want Elemental and Chloro roles for better tanking and healing (but much worse dps).

I dualbox a warrior & healer and i even solo rifts that require 5 or more people and on the plus side i always have a group ready to get some instances done for loot or if i need to farm them to upgrade my gear and i can simply grab 3 rdps which i prefer rdps for less aggro and i like to see my tank attacking the mobs from a melee distance so i don't get distracted.

Dualboxing mages this is a good idea actually i was thinking about this for pvp and i will attempt this for pvp only because it seems it will be most fun for it and my tank & healer combo only for pve of course i cant wait to try out the mages will be great!
