Are attacking hyper skills mainly designed for bossing only?

Those are all keydown skills.

The 8s CD Hypers are all decent for training if you don't already OHKO.

I see it like casting Panic - 30s cooldown and the fact that it takes a swing means it's only worth it on stuff you 4-5hko or more. It was most useful when taking down a single group of monsters took up most of the cooldown time.


Being ridiculously strong is of course gonna simplify training, you just one-shot stuff with whatever skill casts quickly.
