Making the game non pay to win isn't gonna happen.
I'm fine with suits because you don't suddenly turn into a god with 100% more def and dmg.
Sure the accumulated amount does make a difference but it is nowhere near the amount you get from charms.
If you remove charms and extenders or at least limit them so they can't be spammed for everything then you will actually realize that glads can't tank everything and they gonna need clerics and knights at some point.
I'm one of these players that "overstocked" on stuff with over 40 pages of SC that are valuable (destroyed all free suits that don't give stats or very little). However, I no longer enjoy the game because it is just too easy and when I play I just don't use anything despite having enough for me to last few years without spending anymore money.
