I dont think anyone is asking for SMN to be comparable to monk (or any melee for that matter) in single target dps. But many people believe that they should be the highest single target "ranged" dps, considering their drawbacks in the fields of MP sustainability, AoE dps, and Utility.

The FCoB mechanics and superior performance of BLM for both ST and AoE DPS leaves SMN with little going for them.

I don't mind some classes having drawbacks, I actually believe it to be a very important part of class balance. However, SMN looks kind of like this:

ST DPS: Low/Average
AoE DPS: Average
Sustainability: Low
Utility: Low

Shouldn't they be strong in something?
