I've been playing since July 2016 (a few days before the end of Lechenaultia's initial release event) and outside of a two week period last year I've been logging in daily. The game was much simpler back then which probably helped keep me from getting overwhelmed. Back then there were active event missions and that was it; by the time Lavender's event became a permanent reissue my squads were strong enough to survive 80 stamina stages without getting TOO beat up. Granted, having helper squads that could seal the deal in case Astra Galus and Friends got wiped out didn't hurt.

Nation battles were way off in the future along with whale battles too so after logging in it was again mostly a matter of chipping away in whatever the current event was, maybe with some manyu or dragon collecting depending on what day it was. I might have burned a flower gem or six on reissued events to collect the event Knights I'd missed out on the first time around (Lavender to Leche).
