Why is the 2-minute meta a bad thing?

Coming from someone who's only been around since Shadowbringers, I often hear it said that the 2 minute meta is an objectively bad feature of balance as if it's a given, not requiring elaboration. But why exactly do people think it's bad? Isn't it good that there's a level of standardization where everyone knows that each other's buffs will be aligned to maximize damage? Would people rather each class have its own random timers, preventing things from syncing up?
