Honestly the biggest downside of the 2min meta for me is the fact that job design now needs to operate exclusively around it. Everything has a recast time of either 60 or 120 seconds. Every job with a cummulative resource system needs to hold it almost at capacity for the 2min meta downtime to unleash everything in a hectic window.

Like, what's even the point of 4 charges of Fourfold Feathers as a DNC resource if the uses are pigeonholed? You're not supposed to spend them on anything else other than the 2min meta, might as well change Flourish to just proc 4 feathers, since to obtain them you don't have to do anything other than go through your normal rotation.

You can bet that if the 2min meta stays in the next expansion, the new job(s) are going to be just one or two gimmicks and then everything else aligned with the 120s timer.
