Okay so hear me out..
I've come across a lot of ppl online even heard it from youtubers that claim UF "grants" instant pass rush wins.
I really don't believe that is the case. Even on this website it states that "this ability increases their win rate" but in the game the ability only says "Pass rush wins LEAD to quicker BLOCK SHEDDING". Which to me sounds like "If they Win." they get quicker animations. There was a website called abilities.fyi I came across it last year and it had some neat information on each ability. It looked like they had the actual coded response to the activation and what was needed for activation. For some reason the site isn't reachable as of just recently but I found them to be pretty accurate with each ability I tested. For DoN, El Toro, Interior and Edge threat. They all had the same words "Grant" or "Increase chance" to a "Super_Win". UF if I remember correctly only said "on win" grants faster animations.
Some ppl use UF as the only ability but I really feel like its a complimentary ability. I think barno is a great example of what I mean. UF/DoN/Relentless. An ability that grants wins with an ability that makes that process quicker.
Everything considered I hope I made sense. I hope the community receives this well and... I hope I'm right.
