Pick a gametype you are really good at and just keep playing it. I picked doubles because I know that I am a pretty good player and like to lead the team. Lone Wolves doesn't have any structure, you just spawn and kill. Doubles takes strategy and teamwork.
xSpartansWrathx Brigadier Grade 2 at your Service!!!!!!!!! But seriously though, it's so tough to get a level 50
I have twice as many custom games as I do than ranked and social combined. And because I have about 300 xp, you would think that IF I only played matchmaking I would be around General rank.
Since about a month ago I got live, I'm now a Gunnery Sergeant. I've only played ranked matches twice, and the rest of the time its Big Team Social. Not much compared to other ppl on here, but I feel good about it.
