For the first few days you were having great games, your opponents were similarly skilled and played properly, it was fun.
Now the only gun you see is the DMR, anyone that you get the first shot on runs away and everyone is using the two explosives specializations and spamming grenades. The other team just team-shoots with DMRs from the other side of the map and hoards power weapons, and so does your team.
I went from playing fun, fluid games to crap ones.
