I brought this up originally in the tank forums when talking about DRK's gameplay but thought it was a topic that deserved its own thread. Someone linked a Reddit post which I think does a good job introducing the topic

Meta probably isn't the right word since Square intentionally designed classes this way rather than players figuring it out on their own, but basically in Endwalker a lot of raid buffs got moved to two minute cooldowns along with other abilities getting their CD changed to a multiple of 60 seconds. This has the benefit of letting everyone line up raid buffs as long as they're hitting buttons on CD, but on the flipside if you're trying to perform well, a lot of your damage will come from how well you're pooling resources and fitting them under 2 minute burst windows. Or 1 minute if you have a NIN in your group, which I think at this point TA is the only 1 minute raid buff in the game. It basically pigeonholes every class into being a burst class even if it's not necessarily one, and a lot of your performance starts depending on others using their buffs at the right time rather than necessarily on how well you're doing personally.
I brought this up in relation to DRK because outside of your burst window, there's not much going on because a) all your abilities are on CD or b) you're not using attacks like Edge of Shadow or Bloodspiller as often because you want to save resources for bursts. This leads to the common complaint that once you do your opener, you spend 45 seconds doing 1-2-3 until your next burst. DRG got affected by this change because before in ShB, your buffs didn't line up as nicely, so part of its gameplay was keeping track of these buffs and entering or delaying Life of the Dragon depending on what was coming off CD. Now that all its buffs are all multiples of 60s, that aspect got removed and you always enter Life as soon as you can which is a downgrade for me.
Basically trying to see what other people's thoughts are on this topic, whether they think it's a good change, bad change, etc...
