I think the legion changes for the most part are good or a good step in the right direction.
I would remove the deceased feral frenzy movement speed, doesn't make since when you can't damage people with FF anymore. I say increase it so legion can have more mobility
Remove deep wound pausing when mending. With the increase terror radius and deep wound pausing within it, this is too much and makes deep wound worthless and pointless. Would also increase the base mending time.
Remove blood pools/stains being invisible. Once again with FF no longer damaging deep wound and moonwalking essentially being gone, this is overkill.
It has been confirmed by @Peanits on this post" https://forum.deadbydaylight.com/en/discussion/57975/these-changes-needs-to-go? " that FF power guage doesn't completely deplete when missing an attack. It pauses and recharges from the remaining amount.
Apparently their will be an add-on that will still allow FF to damage deep wounds. My guess would be Frank's Mixtape
Personally I don't like legion at all and never been a fan, but I don't want them to be destroyed either.
But I also think legion fundamentally is a terribly designed killer that can't be fixed with buffs or nerfs, and this update/change proves that. You can't fix his problems and make both killers and survivors happy.
I believe he needs an entire rework eventually
