Black widow ability accuracy issue
I am using a r4 4* sig level 60 black widow with a 64.55% ability accuracy fighting classic spider man which should give me an extra 15% for class advantage taking me to 79.55%. In addition to this I am also using her with hawkeye AND quake which EACH give her an additional 15% taking her ability accuracy to 109.55% and yet he still evades her attacks? Can a mod please tell me if and how this is working as intended? This is in a normal quest with no extras, no buffs.
Thank you
