Not to be the Blue Mage evangelist, but it has pretty simply solved the problem by just making it completely impossible to spam all its resources during a single window.
Of course for normal jobs we have too many meta believers crying about it if even a single follow up oGCD or pitiful gap closer hit doesn't fit inside the burst window, even if to think it's a real problem, you have to completely miss that the balancing takes it into account and it's still the top DPS within it's role.
I can only imagine the screams of "jank" and "bad design" if you gave a normal job whole second page of resources that will never be optimally usable within a 15 or 20s burst.
