ok take 5% of that 12.5k dps blm and add it to the 8.7k dps dancer you get 9.325k dps (standard finish buff should always be on and its a flat 5% dmg increase) then add all the percentage from technical finish, about 1-2% per player so x5(exclude hlrs since they won't always be using damaging skills) and then add devilment another around 1% from the blm

so just with that blm alone your contribution goes from 8.7k to 9.575k(1% the low end) up to 9.7k(2% the high end)

Now add 2x 1%/2% from 6k tanks which be another 120-240 dps so 9.695k to 9.940k

Then add 2x 1%/2% from 9.5k to 11k dps which be 190-440 dps so now you would be 9.885k to 10.38k

These are low ball estimates, assumes blm is partnered with dnc, party fully lives, buffs go out for full duration, no hlr dps which in a good group will happen.

I say we are actually in a really good spot as dancers our raid contribution is high enough to be valuable but not so high machinist is threatened which only has tactician(dmg mitigation), i do not feel like we need any direct buffs yet, rng mitigation on the other hand would be nice and sabre dance ogcd when? :P
