Well, I guess Command is my game. I do well in it.
Plunder is such a fucking nightmare, seems like most people think it's "Shoot everyone, only when you can't find anything to shoot do you go for the idol. If people to shoot show up, drop the idol and engage. Rinse and repeat till you lose."
I just don't understand why people can't understand the simple rule of "Someone grab the idol, everyone else escort and cover them."
That's basically why I bailed on Plunder, too.
It's okay, though. Like you, I discovered how great Command is. Plunder was my jam in 3, but Command is too good now. The easy mine kills and generally more-focused teams is a much better experience, in my opinion. The maps feel more balanced on it as well (with Plunder having some true head-scratching spawn locations).
Unfortunately, you still get some crappy teams. I still manage to get between 3,500 and 5,250 depending on the game, though (much more than Plunder) -- I just wish more people would learn how revives help the whole team.
Command's really the best mode right now, I think.
