actually this is the second revamp of kerning square.
technically 3rd revamp as Taipei101 (a Taiwan world tour area that got replaced) was the original source for the original release for Kerning Square content
mmm idk, resources do get reused for new content pretty often. I can't say it'd really justify as a revamp.(less)
look up and compare Taipei 101 to Kerning square, they were slightly different, and the story was completely different; almost like comparing Neo Tokyo to the Neo city theme dungeon.

from ALL their skills?
Shimada heart may be OP but does it really need to be REMOVED?
At best, I could see it getting a cap on DMG increase.
reducing damage on all their skills is the worst idea imagineable, sure add a cap to shimada heart but nerfing the oother skills would make them far weaker than any of the other classes, capping shimada heart would be enough to even them out especially as the only change for hayato since V was having the ability to get more def stat due to the def cap change, before that they were pretty even and some would even have considered hayato to be on the lower end of the damage scale (less)
