Midare Setsugekka doesnt do enough for how long it takes to pull off

[Crushing_Wake]

assuming you dont have Meikyo, it takes 8 gcd to do it once. by that point mnk, is 1 gcd away from gl3 and drg probly already finished all chaos thrust and jumps and full thrust combo

it takes even longer if you wanna wait to do it with hissatsu kaiten buffed mgsk.

i dont mind overly complicated skill if the reward is justified. right now, it barely beats life surged full thrust

This has to be a troll post, lol
Why else would you compare what it takes to get 3 Sen, which are a resource, to what it takes to get three GL stacks? Spending Sen, regardless of how, is built into the class. You only 'spend' GL stacks under the most niche of situations.
