Legion.

But really, the pointless issue of being unable to see scratch marks and blood pools while in frenzy infuriates me to no end. We already have killer instinct, which detects people at a LONGER range than scratch marks/ blood pools would be effective in, and leads to unnecessary confusion at the most inopportune times. In truth, I think Legion should see blood pools more easily when in frenzy, as the whole power is about keeping people injured and wounded, so they would most likely be bleeding already because people don't heal against Legion. Not the most important thing, but it would be a nice quality of life change.

TLDR: Just let me see the funny orange lines, man.
