Both of these are bad options.

The system that we had previously meant that not all jobs synchronized with buff timings equally well, resulting in rDPS disparities. Some jobs like NIN were perennial picks, because a 1 minute buff aligns with pretty much everything. It also meant that your buff windows could be just free dps if they didn't align with mechanic checks.

Removing buffs entirely simplifies gameplay even further, and is essentially a non-option. I'm not sure why this was framed as a choice.

I think a better question is whether burst should be occurring around two minute cycles, or whether that cycle should be shorter or longer. Shorter cycles (i.e. 1 minute) lends itself better to more intensive gameplay and mechanic checks. Longer cycles (i.e. two or three minute) allow us to have job designs that are less timer-driven and allow for a greater degree of actual resource management. One thing that fits in with this is the question of whether you can 'store' your one minute mini-burst to add to the end of your big burst window under certain conditions. P8S was a fight which rewarded this type of thing. You can only do this if gauges are designed appropriately, with the capacity to store additional resources than you need for performing your standard rotation.
