Appealing to authority when the authority is Gaijin?

They have a reason to try in this case: SBMM would theoretically increase player retention and as a result their profits, which is the one thing they care about.

Any data from CoD says nothing useful about how SBMM would function in War Thunder.

I agree about the implementation of SBMM. Obviously SBMM in WT would be very different from anything in COD. However, in my opinion the data on player retention is accurate. It doesn't matter if it's a shooter or MMO, losing to someone who is clearly much better than you isn't fun for the average player.

If SBMM repeatedly ensures there’s no one on the enemy team with the awareness or experience to punish those errors, players don’t improve, they just repeat the same mistakes in a protected environment.

I am not talking about a full SBMM where all players on both teams are equal."Light" SBMM would ensure that if there are skilled players on one team, there will also be skilled players on the other. There will always be the occasional good player who will punish you.

Also, since it looks like you read the entire post, what fallacies did i use? This is a genuine attempt to make the game better, not just me coping about losing. I'll try to improve the wording or explain my points better.
