Easy way to fix spell & skill speed before Heavensward!

And SMN would burn out of MP even faster. The extra 60 MP every minute would be entirely subsumed by having to cast dots more often. Even if you applied the same effect to Aetherflow, it wouldn't be enough to keep up with the expenditure, I don't think.

I believe he's talking about spell/skill speed increasing the total number of tics that occur, not just having the existing tics go occur sooner (shortening the duration). So you have a breakpoint that turns Bio from 6 tics at 18 seconds (1/3) to 9 tics at 18 seconds (1/2).
