Picto makes the game less fun

[Ramiee]

And what are the issues with PCT?

It's incredibly strong and it's not even in fights where it's greatest strength is on display. PCT has tons of movement, a decent mit, one of if not the strongest burst in the game and a filler rotation that isn't rigid.

M1-4S do not have downtime often, downtime usually is a detriment or a pause to jobs, to PCT it allows them to effectively have free muses. This will make it extremely powerful in these situations.
PCTs only disadvantage is that it doesn't have a Res and it's non-burst damage is bad, however in a game defined by a burst meta this disadvantage means nothing.
