Are attacking hyper skills mainly designed for bossing only?

"Hyper skills are not affected by buff duration increase or cooldown decrease."


But it's anyone's guess that Nexon could mess this up despite what it says.

Yeah I've seen that, but I've heard different from players who have hypers..

You are mistaken. I've tested Mercedes hypers personally and had a friend test Kaiser. Neither buff duration nor cooldown reduction work with hypers in GMS.

I cannot test cooldown ignore.

I've heard against that, but I'll take your word for it.
