Earth and Moon does not stack with Ebon Plaguebringer (or Curse of Elements, these are in a common non-stacking debuff group). Ebon Plaguebringer is quite a bit better group effect from a practical perspective on trash pulls, since as a disease it will spread to nearby mobs and amplify AoE damage, while Earth and Moon will generally only affect the current targeted mob/boss.

A boomkin still brings solid dps and utility which you wouldn't get from a 4 shammy+tank team such as improved fairie fire, G/MOTW, and Insect Swarm (boss hit debuff).

That being said, I have two boomkins just sitting around at level 80 doing nothing while I run my DK + 4 shammies through heroics; I just find the simplicity of this setup very appealing and I love 4x healing stream/4x mana spring totems. As others have point out, to maximize DPS as a mage or boomkin requires altering casting in response to procs, which just isn't going to happen for a multiboxer. Shamans don't have any such proc-based spell rotation changes.
