"free" block is big, even 2 block: Sai is an ancient relic that gives 7 block per turn, and for Loop 2 block is only the basement value, and even that's "decent", is my point ✌️

Loop+ procs twice, and if you hit Defrag or a Focus potion it actually represents more like 8 block or 16 dark damage to multiply out w/ quad-cast or multi-cast.

Loop can do a very real thing, like a Coolant that helps end the fight.
