The current system in place is utterly moronic. This system doesn't reward good play, all it rewards is who is able to spam the most battles. There are players that aren't even winning 45% of their battles over 5k rating. All you have to do is 1k dmg in an OP tank for 1k battles. This shouldn't be rewarded. An afk will only lose 10 rating points. -10 for doing absolutely nothing. This is a great system. For a loss the starting amount should be -40. And as you work your way up chunks are taken out of the -40. +3 for every 250 at tier 8, 350 at tier 9, and 450 at tier X. A kill should only be worth +3. And a high caliber should be worth an extra 10-15. Same should be used for a win except an automatic +20 or +25 should be awarded for winning. It shouldn't easy to maintain a high rating but rather a high degree of difficulty.
