OK, looking through the last 5 of them, there's a recurring theme: you had idiot teammates. Big time. Some of the teams were a little lopsided against you, but nothing to really write home about.
You're also at least half way up the XP chart or higher on those games, so you're pulling your own weight more times than not.
I played a game just now so I could take some screen shots and show you how things go pear shaped one way or the other. So here's the game I just played in a KV2:
That game could go either way. It looks just a tad in the other teams favor, but not much.
So here we are a few minutes in:
Notice that the first guy to die hides his stats. (For the record, I usually do too. I took them off to use XVM but for some reason it's still showing me as blocking stats.)
But yeah, he went full yolo and got blown to bits. Here we are a bit later:
Notice that two of the better players they had bought it by then. After that, it was all down hill from there and we won. I got blown to bits by an SU-100 I never saw, but this is how it ended up:
It's not that either team had any real advantage to begin with - it was pretty close. And it's not that any number of people did anything really that wrong. It just worked out the way it worked out.
That may look like a wipeout, but it wasn't. The majority of them died at the end because we had them from two sides.
Your games look very similar that I've looked at so far. It's just really rotten luck more than anything you're doing, or anybody else for that matter.
