I did not feel any difference facing them in T4s before or after the patch. They simply changed configuration. I perfectly know what a death squad is, and I read these concerns, but lets face it: it was more historic events, like disappearing players, which made death squads disappear, not squad sizes. People have advanced, and I actually saw a lot of T5 mk3 esb players playing some T3, with equally strong gameplay, but way more fair because at least you could shoot the rest of their team to shreds.
If all on your side are in the same squad, it is a pubstomp match anyway, no matter if it’s 4v4 or 3v3.
If you don’t squad up much, it should not bother you. Facing 6 (2*3) players from the same channel (which is much more probable now) however isn’t really more helpful, than facing 4, and the difference to facing 8 (2*4) or 6 is really negligible. You still have a major impact on battles based on your pilots, not just on your squad size.
I read these arguments about squads influencing this or that a lot now, and they are still unconvincing. Yes, really strong combos are possible, but usually its still the team adapting to your combo which decides, and as a decided solo player you might be more opportunistic and aware of what people do anyway, which means you can form combos with others on the fly.
But many people learn this actually by flying with others. 3 people - as i said - cannot take up a guest spot, because 2+1 is simply no squad at all. 4 was a minimum I actually hoped it to be increased at some point, but it is true, anything higher than 4 would basicly make MM harder.
I do believe, that teamplay makes players better, who are not naturally into the game from the start. It also offers some of them to unveil their potential or ask questions about the game to an audience they bond with. 3 or 4 makes a socially big difference in this case.
I see a lot more changes because of the patch content, than of the squad nerf. The change there changed little about matches being unwinnable sometimes. And this was already an expected result.
Of course this is highly subjective, and based on my experience as someone who almost always squads up (but I do solo from time to time to get into winning matches more often), but also as somebody who is mostly used to and fascinated by team coordinated gameplay.
Of course it was already also mentioned by Antibus, that they are going to monitor this situation, so all this is is just pep-talk.
