If Atomos can control time, maybe it will be an avatar we use all the time by allowing us to warp time so we get shortened rage and ward timers at some (hopefully) reasonable MP cost/trade off.
SE had openly mused about this idea before have they not?
I'd take that Atomos over any fancy damage or situational group buff mechanic. But I fear we'll get a version of the Corsair's 2hour ability with Atomos where all JA timers are reset and there's a high chance of resetting 2 hour timers at the cost of the summoner's entire MP pool. And it will be another group buff thing that SE still think we should focus more on.
