Who thought this is a good idea ? Like I really want to talk with the guy who came to the meeting and proposed this, it literally makes the end game fights which are way longer because of the bosses HP, fully RNG, literally there's a 3% chance across every debuff removal/application that the boss will resist even if you have 500000 accuracy.
If a boss requires 170 acc to apply debuffs, then MAKE it work that way, stop implementing RNG in fights as well.
