It is technically "competitive" because you are infact competing against another team. But you can't expect to group with completely random people, some of which don't have the means to even communicate (depending on game) and have that team be that competitive.
When you do random matchmaking by yourself and you aren't in ranked play, you are at the absolute lowest tier of competitive gaming and getting mad at that is pretty lame.
If people care, then they should get into games that have ranking systems. LoL has one, SC2 has one, even CoD has it now. If you are actually good, you will level up and leave the lower leagues behind you.
