Late Comer CQC discussion

So I've been playing Ed for almost 2 years. I'm almost at elite status in everything. Currently at 32% deadly in combat and elite everything else. So for something new I figured I would try out CQC. I know many say it's almost a dead thing. So far I've made it to level 27 but I have some questions. Many times I've been in death matches where there are 2 or more people and if I win a couple of matches everyone drops off at once. Almost like they are in their own group and I interfered. Sooo–is there a way to invite other people into a deathmatch? Are there still any PS4 people who would like to set up a day/time for matches? And lastly, as I've been in different matches I have written down certain names of other commanders who were close to my talent level–is there a way to specifically invite them to set up future matches? my commander name isa Airchair94,lol.
