Being forced to play according to the game's schedule instead of yours.
"Entering certain events such as Monsterwood or Grand Prix pushes you to play after a certain amount of time in order to avoid missing out on getting the maximum rewards. This is in addition to the two battle passes in the game which must be completed before they expire in order to get the maximum rewards. As a result, you may feel forced to play at inconvenient times of the day."
"Guild feature where all players fight to defeat a boss, but you get points and rewards based on the damage you do and if the boss gets to low health you get less points because you’ll be doing less damage than you typically could."
"Rewards that are only available at certain times of the day before they are removed. There are some limited time log in gifts, as well as daily and weekly challenges that expire by the hour. In-game events last only for a few days or up to a week, or can only be played at certain hours. There are constant battle passes that are time-limited, meaning you would have to play constantly every day to complete it in time."
