I absolutely love Octavia, but one of her abilities makes my eyes bleed.
When you cast Metronome, any buffable action (eg. crouch, jump, melee, weapon attack) releases a blinding white circle from the warframe. I have a pretty good eye sight(so far) but even after playing her for a small duration of time my eyes get extremely tired.
See a video below to illustrate the problem. Every buffable action releases the white circle and there is no cooldown on this visual gimmick.
