So after seeing the totals today, I am so happy that I played on roster 2 with my second account. This way my 257 #1 on roster 2 kills counted for something. 267 was the #6 spot, so all of those kills would have went for not had I played on my first account.
The only thing I am mad about was I am a level 80 on second account and won't prestige, and I am 1,500 xp away from prestiging again on my main account, so all of that double xp last night did me nothing. Actually I would have been receiving Quad xp since I had a couple hrs. left over from before.
