Full XP with every option in portal

I think it is self explanatory. Why we cant have full xp with every option in portal, why you care if anyone want to farm xp or just enjoy to unlock every weapon and attachments and vehicle weapon system with bots without getting stroke because of cheaters and really good players? This game will be dead if the new game comes out and it will be good. So pls allow us to have fun pls..... be a good developer team and let the players enjoy it, if we spent money on this BaTtLeFiElD game...
