If it doesn't do stamina damage, what does it actually do then?
Fast unblockables can be dodged up to the very last second. The only reason people think they are OP is because FH is a unique game with new dynamics not present in other games and players haven't conditioned themselves appropriately yet. In 6 months, as long as there is no over-reacting nerfs - this won't even be a thing anymore.
Aside from the fact that they already give out free damage and possible set-ups?? The fact that they allow for a huge disparity of offense potential between those who have them vs those who don't??
People complain already so much about defense yet they don't see how stamina damage encourages more defensive play because it allows putting the opponent in exhaustion without them messing up their own stamina management.
"Just dodge it" only works on retards who have no idea how to approach an opponent. Good players use them when they have a good chance to hit, if not when it's guaranteed. And besides, some fast Unblockables don't even have a big punish window and at most the punishment is...a Light? They are part of the reason as to what makes the game unbalanced because they are simply just very good tools and are essential in separating tiers.
Is it a coincidence that Kensei, Orochi, Raider and Berserker are considered in the lower tiers where as Warlord, Conq and Warden are among the top?
Just look at all players who main those characters and how they're scared that their fast Unblockables to be nerfed because they know that they're good tools.
If stamina damage were removed, they will still be really good. It's just that opponents on the receiving end don't have to suffer consequences from exhaustion even when they already manage their stamina well.
