if they bring it back. they can't bring it back the same way. the timer was obnoxious in that if you wiped twice quickly you had to wait despite starting over. and if you had a long boss encounter you could sometimes awkwardly try to pop a synth mid fight (awful). I think they need to allow for one synth pop per full wipe while not in combat. That said, I prefer no synths to the awkward cluster f of a system in Destiny 1.
