2 minute burst timing is really good, I will never understand why people are against it. It enables encounter design to be complicated while also having burst design be complicated. Ideally encounters play out like this when things go smoothly: You do burst opener, then when you're in regular rotation a complex mechanic will occur, then you do simpler 1 minute burst during moderate mechanics, then you do 2 minute burst during a part of the fight where nothing is going on, then a complex mechanic occurs again. This repeats itself throughout the entire fight.

If this doesn't happen it's either one of two things: 1) the encounter design was bad, 2) the group didn't line up their cooldowns properly.

Anyone who disagrees with the 2 minute burst timing just doesn't understand the fundamentals of encounter design in this game or what the developers are attempting to achieve. Which is okay, most people eat mcdonalds regularly.
