I am not so concerned about pub games. Those I can tolerate to some extent but what I can't stand is absolutely trash matchmaking in ranked.
90% of the time I don't have a premade squad and I am often getting matched with people from gold and/or level <150 (I am plat 1, lvl500) who can't even use their ults.
I simply gave up on ranked and in fact playing the game much less now than ever before because of this.
Respawn claims SBMM is working well and help with player retention .... i call it complete bs and disconnect from the actual state of the game.
Perhaps they don't account for smurf accounts who make their statistics look good but as with statistics, you can show (or see) whatever you want, regardless of actual data.
I have never seen anyone asking for SBMM, yet Respawn won't take a step back and fix it or remove it. Developers not giving a rats * about community feedback about such a crucial feature of there game will eventually lose their player base to another studio/game that does ... and we have a pretty good contender coming up very soon so let's see how this plays out.
