While EAFC may not match the event quality of the first five seasons under the FIFA Mobile branding, its gameplay is better than ever. There are still issues—occasional passing problems, bugs, AI adjustments that sometimes go too far, and the ever-present cheaters—but at its core, the gameplay is at its best.
Ultimately, without revenue, there’s no funding to improve the game, maintain servers, or justify EA keeping it alive. Like any game, its primary goal is to generate profit, and EA as well as other gaming companies have shut down many online servers for games that have been phased out in recent years for this very reason, profits plummeted.
If you think EAFC's pack luck is bad, it’s still far more transparent than many other mobile games (some titles are quite surprising). Look up some videos on the topic—they might give you a new perspective.
