You still seem to be stuck on this one point. Nothing that you are talking about here is a consequence of buff timings.

The comp choices on the first few weeks were a reflection of dps inequities, not due to the timing of raid buffs. RPR's Double Enshroud lines up very naturally with 120 second windows, but also offered the least dps out of all melee jobs by a fairly significant margin. Players who are determined to get an early clear are going to naturally migrate towards meta picks when there are gross inequalities. That in turn gets reinforced by groups with clear potential selecting for jobs that are going to get them that clear. But your point remains irrelevant to the discussion around buff timings. The solution was and always has been to achieve dps parity within individual roles. Has nothing to do with your 'two minute meta'.

The reason why nerfs were required for Heavensward Savage tiers was because people found them to be too difficult. Difficulty has nothing to do with the timing of raid buffs.

You can complain about whatever you like, be it balance, difficulty, or what not, and I'm sure that they're all important issues. But your entire post has no relevance to the timing of raid buffs.
