The VIDAR should be 9.0 your just where you need to be.
Tell what to do against a XM803. Still the fact is that I said I mainly saw it because I played 8.0 a bit longer with my VIDAR. That doesn’t mean that there is only a proplem with the sweden 8.0 lineup its basically most 8.0 Lineups. still I’m not talking about that the I have big proplems with my VIDAR but I also have 7 other vehicels in the 8.0 lineup which struggle with uptiers. I also played some other nation.

If it is that easy wouldn’t complain about it.
You do the same thing you do with almost every medium tank in the game, shoot anywhere but the front plate and get a free kill. You can even hit it’s extra thin side from the front
