Auto winning missions are limited by skip tickets (rare drop), making this game time consuming and boring to farm. The subscription doesn't provide infinite auto wins- it only doubles skip tickets to 2, whenever they drop. Cannot pick pity prize after 100 poor gacha pulls. It sucks that events with 4 star gear aren't permanent to help beginners. Stamina is full after sleeping for 10 hours, so some recharge time is wasted.
