You know what I miss?

Dismantle.

If I had Dismantle, I would be okay with MCH's current dps output.
But as you said, ranged DPS are balanced as if they had much more utility.
Refresh was almost mandatory but now healers and mages don't need it anymore.
Palisade was niche but neat, I wish we still had a single target mitigation even if I have to macro/target the tank.

I just wish we could at least have the tools necessary to excuse our poor rDPS, SQEX needs to acknoledge that we're not in HW or SB anymore, there is no piercing debuff, there is no refresh anymore
