With the new Paladin boost, it would almost be worth making a Paladin + Monk combo for 2 boxing. Got heals and tanking in one character, and DPS in the Monk.
Also
The way I'm using my 3 accounts is 1 = Tank-types (Monk and warrior), 2 = Healer types (Druid, Shammy), 3 = DPS-types (Mage, Zerker)
Will my monk be a viable epic-farmer past 1.5s? Or should I focus on my warrior with the druid to heal him? Will a 1.0 Warrior be able to duo his 1.5s with a healer (preferably druid) if said healer has their 2.0 already?
A monk solo can farm 1.5 and 2.0 pretty easily, but they have to be decently geared, as any other character. A warrior isnt very good until he gets his 3.0s and anger augs... Same for Monks. You have to work towards your 3.0 weapons.
However, its not as hard as you may think. 1.5 and 2.0 are honestly the hardest out of the 4 (5 really) epic upgrades. 2.5 is breaking barrels, and 3.0 is one mob that i'll kill for you if you send a tell.

Anyway, as i was saying. Paladin and Monk (3.0'd) would be a good 2 box combo imo. If you ever decide to work on charms and stuff, someone mentioned in another thread how much healing power came from a paladin with Oracle charm. That paired with Monk natural DPS is a good combo
