Reinstall this game because you're bored!

While I can definitely appreciate your frustrations with cheaters. . . they've been around for as long as I can remember.  This is nothing new.  Cheating in competitive video games is and always will be a challenge for studios.

Packing the best cards. . . you have to have realistic expectations.  The percentages are published; they are LOW.  You have to be very lucky even when opening the highest odds packs.  Promo cards, even the bad ones (lol), have a low percentage to be packed. . thats the nature of FUT.

Gameplay - Alot of things go into your connection and gameplay experience.  Console version, if you are PC, the power of your PC, your internet connection, your data provider and which infrastructure they utilize, the connection of your opponent, the servers.  Gameplay is inconsistent because everyone's connection is inconsistent.  The ONLY way to have a consistent gameplay in today's world is to play offline games with no reliance on the internet and to have a system that is well equipped for the game.

If you are this frustrated, sometimes it's good to take a step back from the game for a while.  Gaming is for fun and competition, not for stress and frustration.  Now the reality is even when it's fun it can be incredibly frustrating!!
