Are attacking hyper skills mainly designed for bossing only?

I have no idea why it's got its own buff icon, but I love that because you can extend its duration and lower its cooldown

"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.
