Move Glare IV

[Reinhardt_Azureheim]

It’s just that Glare IV is a GCD and thus you’re supposed to use it instead of Glare III.

So replacing Glare III makes the most sense.

No it doesn't. Yes, you are supposed to use all stacks of Glare IV before the effect fizzles because it is a damage gain, but there is absolutely reason to hold the stacks individually if it allows for better movement, similar to how Red Mage has Dualcast and can manage additional instantcasts with Acceleration. Or Pictomancer with spending white paint on Holy in White for similar purposes.

You can do Glare III -> Glare IV for movement -> 2x Glare III -> 2x Glare IV for more movement for example without having to cut Dia short or blow lillies if there are moments you might want to hold lillies a bit. And we have yet to see what raids and additional content will make us do.
