Battleground suggestions - BG matchmaking / free action potion

Since I recently returned to Warmane after few years break. Would love to see some changes for battlegrounds.

- MMR rating for battlegrounds for more balance. (Factors like BG Winratio, Equipment, Group or Solo, Healers per team - no respec in BG prep.)
- Remove free action potion (30s 2min CD full CC immunity) or at least make it cost way more on Blackrock. (Makes certain classes completely unbalanced, Rogue/Mage near useless and Boomkin/Ret way too strong)

Cheers

You will see those changes when I become president of the United States of America.
