Well skeletons in your closet is easy, but I can help you if you want to, tho im kinda bored of horde unless someone wants to do snowblind horde. I'm always happy to play a good non-lag game of submission with ya so well see maybe later this week?
Hey i got the exact % for the exp in gears
Here they are: courtesy of und3rdoggy
This shows that for every point you get in game how much percent of that point you get.
Annex -- 0.26%
Execution -- 0.98%
Guardian -- 0.91%
Horde -- None
King of The Hill -- 0.28%
Submission -- 0.49%
Warzone -- 1.00%
Wingman -- 1.09%
Basically just multiply your score by the percentage. I.E: If you scored 1000 points in wingman you'll gain 1090 exp, (1000 x 1.09 = 1090)
