v.154 – Sword Art Online Update Notes

The Blaze Wizards level 150 Hyper Skill, Dragon Blaze, is supposed to have a cooldown of 90 seconds (it says so in the tooltip) but you can use it as much as you want. You can actually rapid fire it by keeping hold of the skill key, which is absolutely insane.

Ya, I tried a few levels on my BW using strictly just this, but I found that just spamming orbital does more damage.
