To this day, I still fail to understand why you have always been able to right-click off feral/guardian druids' Leader of the Pack, a crit buff with no negative effects, but you still can't do anything about Aspect of the Daze.
Aspect of the Cheetah didn't daze me on the Blade Lord on normal mode, so I don't really see how it's bad on that phase. The only damage going on is the constant damage every second, which did not daze me.
You had the minor glyph. It definitely dazes you without it. Never use pack on that fight.
