EA: PLEASE Improve H2H Play

No problem. Hopefully, this will encourage people to actually assess and troubleshoot their networks first, ensuring they fully utilize their connection rather than relying on the default settings from their providers, which often involve subpar modems and poorly performing Wi-Fi access points. This is a very common issue, and unless someone is IT-savvy, they're typically left at the mercy of the providers. EA doesn't have jurisdiction there and would get nowhere even if they wanted to or cared.

Keep in mind that visible ping differences, especially in global reach games, are primarily a result of where you connect locally. However, in head-to-head matches, there's much more involved and it comes down to how the game is packaged and the IT/Network infrastructure behind it. Even with cloud computing, latency issues won't be eliminated because they are constrained by the speed of light which essentially carries your data around the globe in fibreoptic links (hence my reference to sub-space communications from Star Trek or figuring out how to use Quantum Entanglement to carry data, then we can say goodbye to latency).
In-game Latency differences become even more apparent when all players connect to the same centralised server in FPS games like Quake or CounterStrike or Fortnite. Locals to the server might experience sub-10ms pings, while players from across the globe may face 300-400ms, causing noticeable warping and frustration to the intended local player base. This issue has been around since multiplayer gaming began and it won't go away, what EA should be doing is trying to regionalise H2H as much as possible and even out the top championship tiers where 2 matches are played, one home and one away to progress further

As for support with the bugs and issues within the game itself (not just FC24Mob - but all games), it's a balancing act. Bugs are typically unintended flaws in logic or coding, and while some are easy to fix, others might resolve one issue only to introduce another.
Ultimately, the main product needs to remain functional, so we don’t want fixes that break the game engine.
Testing in NPE (Non-Production Environment) is quite different from what happens in real world and there is so much you can simulate. You see some of EA's FC24 NPE build in Antwan's streams.
