Well, you're wrong. I've been playing objective. I've been playing this series for 23 years (BF1942). I'm not new.
I'm not interested in KD. It's the thing I pay the least attention to in my stats. If I mention it, it's because it would be difficult to distinguish a real profile from a cheater. I don't know if you understand what I mean by this. That's why I ask that only stats be counted when killing a human, not a bot.
Regarding full XP, I think it should come back and allow you to unlock all weapon attachments without any issues, as long as the fake stats in profile don't count (kill bots). Simple as that.
