You know what, you're right about that first part of the sentence. But there is also a reason they are all gone now. They are largely a bad idea because mechanics make them inconsistent, just like they do now in this game. And as for the second part...those are literally just enemy mechanics. A tail smash is a boss mechanic that prevents you from getting behind an enemy to do those back positionals. So like, what's the point of having a danger zone AND being punished via doing subpar damage?
