Low XP rewards since few weeks

Hello everyone,
So just a few day ago and after a short little break from War Thunder I decided to Grind the Israelien ground tree. But within the first few good matches I started to notice that the ammount of XP I got is very low in comparision what I used to get with other tech tree non premium Vehicels in the past and the same performance as now.

I thought it might just be because Israel starts at rank 4 so to nerf the grind a little bit rank 4 has lower XP multipliers which is infact correct, compared to vehicels at the same rank with the same BRs Israelien vehicels have low XP multiplayers than other Rank 4 vehicels.

So I expected it to get better at rank 5 where they got better and more normal but the rewards are still low.

I just played a match where I got 8 kills and we even won. The match lasted for arround 7 minuts and all I got was 5,6k XP.
This feels very low and I’m sure I used to get much higher ammounts just a few months prior.

This is just an assumption and might not be true. I just wanted to point it out and see if other noticed the same problem.
