Raid buffs force you to think as a team about when you want to enter into the burst phase of your rotation. This has always been a part of the game. The problem is that less experienced players tend to ignore all this and execute buffs whenever it's personally convenient, which then amplifies the performance difference between skill levels. They've historically tried to reduce the amount of damage that comes out of such buffs, but at that point you might as well just remove the buffs altogether and turn dps into a single player game.

By moving these buffs on to easily recognizable integer multipliers of each other, buff timings start to make sense to even to average players and they start to think about them, because the LCM is always 2 minutes. The fact that so many players can now parrot out the phrase 'two minute meta' means that they're actually finally starting to think about coordinating their burst with their team, which is a success story by my book. Could they vary some of these windows such that they're more or less frequent? Sure, but the LCM should probably stay at a relatively consistent number.

Since the OP is around, I'll just add that I can appreciate what they tried to do with RPR's buff window, even if we do get double taxed for it. Void contracts are all about making a bargain, and Arcane Circle is no exception. You grant your teammates power, but you also absorb power from them to perform Bountiful Harvest. So you can think of it almost as a reverse buff in a sense, in keeping with the job theme. It does, however, mean that you get doubly penalized for dead or out of range teammates. You can't win them all.
