FWIW, the EUTZ peak in PS is larger than the USTZ one. There seems to be a lot more storyline activity during the (late) USTZ though? o.O (Also, we have terrible lulls lateEU/earlyUS and lateAU/earlyRUS, but that's beside the point

besides, having lulls in activity can be good for getting annoying grinding out of the way without stepping on RP availability too much)
P.S. Confirming that grinding isn't as soul-sucking since the last patch.
