Well the skill based matchmaking has its own downsides as well, so I doubt it would solve your problem. Personally, I prefer the absence of skill based matchmaking in Warthunder as that makes my games feel less stressful compared to games with it.
Seems like you don’t really want to work on improving your skills in WT and your regime is to just play a few matches for fun and then get out. Then I would strongly suggest to play some single player games instead, where you can tailor difficulty to your liking (I heard that Gunner, Heat, PC! is good single player tank game)
I see this commonly when people treat online PvP games as something to relax at the end of their day, but end up getting frustrated by losing their precious few matches for the day and unfortunately this is common complaint with much more strict matchmaking than here.
EDIT: Don’t get me wrong, I see your point and although I enjoy WT now with decent win rate, I know how it feels to be on the other end, finishing games with little to no kills.
I didn’t really have fun in WT and had low winrate until I reached 3rd rank in my first tech tree only then I started to really pickup on how to play WT properly and started having more success overall. But that requires to invest quite some time and effort and if you can’t do that, I doubt that Warthunder is a good choice for you.
