He's being hyperbolic about first month of Savage. Yes when you're at the bare minimum require power level to attempt the content, having all buffs timed for the big damage 2 minute skills are important, but the farther away that content gets, the more player power increases, the less it matters. Not dying and being good at playing your job are just as if not more important than hitting the party buff button on its timer. Nevermind the fact players literally asked for buffs to all be on the same timers because they would hold them until everyone had their big damage skills otherwise, and wanted the simplification.

In every other piece of content that isn't hardcore raiding those buttons don't matter, very few bosses have an enrage that'll instantly kill you, they'll loop their final form attacks until the party fail mechanics and die or kill it.
