First off, as a general rule of thumb, you can not declare winners until a thread is finished. Not only is it against the rules, but it tis better to encourage people to read the actual thread and udnerstand all arguments before voting even though most people say "X Character wins fra.
It isn't arbitrary. Unlike the other games, the Ashen one canonically does not go hollow regularly upon death. Hollowing is only initiated through dying while holding dark sigils, and can be readily cured with purging stones. Granted, in the Lord of Hollows ending you do need to have the required amount of purging stones - meaning they do at some point begin to hollow - but not only can they cure it like I mentioned, there is no evidence that hollowing is entirely debilitating to the player character. Especially in the lord of hollows ending, where they embrace the undead curse, its shown in each game that despite hollowing the player character can resist. So no, infinite respawns is not a cop out.
So is there a bonfire in this matchup? In which case, BFR has no major effect since the Ashen on can teleport back to the bonfire basically instantly. Using a homeward bone or the bonfire sword piece.
