Higher Rank ground grind is pure malicious design

I had as perfect game as possible with 12.0 stock light tank, match took 7 minutes but I was only in one tank without dying, so consider full uptime. I spotted, killed some, assisted some, even capped a flag. In the end, I got mere 7.2k RP with 2005 score… I will never find similar game because enemy was reckless, map was great etc. It will take maybe 70 full games only with this tank to spade it.

Also, I am assuming I got 7.2k RP with 200% booster and good game. Is this a bug? Please tell me this is a bug.

What vehicle did you use?
