You also missed the flare buff, flare being instant cast shortened its GCD and made the rotation more accessible and flexible. It’s relatively a larger buff than the raw 3-3.5% that comes from leylines
And estimating 7.1 from 7.05 is exactly what I did, because doing it either way ends up achieving the same thing, either apply the buff on top of 7.05 or estimate the relative drop of the jobs and apply that in reverse. Either way it comes out roughly the same. Specifically because you can see that even though the skill level went down, BLM went up by 5-6%
