Why is SMN DPS so high?

[Yenn]

So now all should welcome a SMN for the Demon Wall!
or not.

I run Amdapor Keep with a BRD, and we kill the Demon Wall before it spawns flies. I think you're just playing with bad players.
In this particular case, I do much more damage than the BRD, because the encounter is so short that starting with 6 Aetherdams is huge.
