Weapons don't have the correct damage bonus

[wooden slate]

Picture 1, 2, 3 are my Seven. With a 561% water damage boost and an equipment score of 544, the damage dealt using a water weapon is only 78? I've tried it on many enemies, and the damage is basically around 70-120
Jimmy has a similar situation. Picture 4 and 5 compare the damage between my friend and me. We've adopted the same skill nodes, have an equipment score above 545, and around 380% impact damage boost, yet the damage difference is tenfold

this is just because of how gear score works, 544 and 545 have a pretty substantial dps difference

annoyingly with how attack and defense rating works, a higher attack rating stat is the more important one for dealing dmg in epic missions

I also tested it when the score was 545 or above, and the water damage bonus was 561%. The damage caused by the water weapon was between 140-210. I didn’t find any friends to compare with me.
