A casual player may only have those few hours to play, and with daily commissions and gatherable resources requiring maintenance, it can stall a player\’s progress by a lot. Hardcore players may also be in the middle of grinding resources or chests, only to be stopped by a maintenance screen that won\’t let them in the game. There are also monsters that respawn after a period of time that players may want to optimize killing whenever possible. The biggest factor to keep in mind is Resin due to its small maximum capacity of 120 and a slow recharge time of 8 minutes for 1 Original Resin. Players may want to use it as effectively as possible. Even if the game is down for a few hours, that\’s about 23 Resin gone to waste if a player is capped out, which is enough to get loot varying from level up material to rare artifacts.
However, there is a small requirement all players have to meet: reach Adventure Rank 5. Fortunately, this does not take a lot of time to achieve either. So people who have been wanting to get into the game could join before maintenance times, hit Adventure Rank 5, then reap their rewards. Though obviously it may not be worth the effort to join for a single roll, and just wait when a special event occurs.
When the game is based around real-world time, it is usually a smart move for gacha games like Genshin Impact to provide rewards when it is down. There are so many resources, chests, and dungeons to maintain daily so a few hours of downtime can be a huge problem for a player. 60 Primogems per hour seems like a decent reward to players for doing nothing, and any less would feel bad for players legitimately disrupted by the maintenance.
