Curious on opinion. Smn or Mch. Which would you pick?

[AskaRay]

If You like to support your party, SMN is better right now.
MCH can bring TP/MP regen, but at the same time You are gonna do less damage, I mean, You are helping with TP/MP regen, but You are not helping doing the worst DPS of the party in a DPS slot.
SMN can raise in combat + Virus + worth DPS slot, I mean, like SMN you can not bring TP/MP regen, but You can Raise, making healers dont spend a lot of mana, Virus in high damage phases and finally You are a real DPS, You are using a DPS slot, and You are doing DPS.

If You don't care how useful are or are not in the party, You should play what do You enjoy, however, If you care to be useful, SMN is the right answer.

You are also forgetting MCH's Physical and Magical 5% resistance debuff every two minutes, and to mention their Attack/Magical damage down debuff every two minutes.
Adds up, you know.
