Hey there abicool123.

There isn't currently an option to invite your friends, but we have found often times if you and your friend start a game at the same time you'll join the same room. This isn't a for sure method of playing together, but it is a current workaround.

this is what happened with ghosts and ops 1 and 2 etc, i knew ghosts was bad for lag comp but i still bought it, i still play ghosts just for a bit of fun.. i might buy it in a few weeks but used as i wont fill activisions pockets anymore for churning out
lag infested mp lag comp like they do now, titanfall or this?

i dont think it has anything to do with your internet, ive played on ghosts for months on a great connection and a few months on talk talk (worst ever connection) and they both played exactly the same, i think its just a take it in turns thing, they try
to share it out but even when i win at ghosts or get the highest score im thinking am i good or is it my turn for the lag comp cr?p, dont see much point in playing tbh
