Limited time offers with unnecessary urgency.
"Every event there is new items with 2 weeks limit on items"
"Tournament, Bundles (they called it Packages), and Advertising Offerwalls (who knows...)"
"really a lot of limited time offers, sometimes multiple in parallel"
"New characters are only available for 1 - 2 weeks, afterwards, they take over 2 months to appear again. Some of these characters are really overpowered. There are also limited time offers which usually read 'Limited time only' and even have a 24 hours timer (the usual), but they stay for way longer than those 24 hours, they just reset the timer but make it seem urgent. There's also battle passes which contain (new) characters or weapons."
