"Plenty of story events that could easily be added to the Chronicles or Open World sections, are instead made available for a couple of weeks. Some of those events contain continuity with previous events."
"Items in shops (including the premium shop) rotate. Some items from closed beta and season passes have not returned and can only be gotten by trading with other players."
"The Battle Pass has weekly and daily quests for Battle Pass points. If the player does not complete quests before they expire, they will not have enough points for all the rewards before the Battle Pass expires, unless the player purchases the points."
"Daily timers with resource caps that mean they need to be used or stop accumulating. Unions are under time pressure to take objectives as a group. There's always some personal timer or another finishing up and requiring attention"
"There are limited time events sometimes with cosmetic rewards that are unavailable any other way."
