Yeah, the double XP just seems weird. It's not double of any number from what I've can see, it adds a bit here and there plus a small bonus XP that doesn't add up to double XP overall. Then in another game, I'm getting like 3x XP overall.
Oh well, on another note: I fucking hate my gaming friends. They descend into rage-whining in no time, they aren't really doing any teamwork, when you finally work together and give them some valuable information or want to have them kill something they run around like headless chickens right next to you with the response "LOOL".
The other day, I had snuck all the way around the map and the enemy to get behind a tank that was sitting on a hill 'sniping' everybody - Excellent tanker. Get behind it and place a spawn beacon for my engineer ( Throughout the entire match ) friend, it was already smoking and just needed a shot. He then decides to spawn as a Support instead with C4, barrel towards the tank which made him turn around and kill us both. Such a small thing but it just does my fucking head in. I'm not pro-elite-über skilled player but I just expect some ability and some brain power but it's just fucking stupidity all the time.
Apparently getting some friends together and actually enjoying this game, getting some teamwork going is the hardest thing ever. Rage fest from start till finish. When the night is over you just have that gut feeling of anger and "Why did I waste my time".
