So I also play a bit of Bc2 and usually browse trought bf3 foruns and i found out that some players would like to see a brink medic system implement there.
In bc2 a medic uses a Defribulator and instant revives you, the issue with it is that sometimes you get revived in front of a enemy tank or in front of a enemy and since in bc2 the k/d is kinda important players get mad when they are revived and that happens.

Its cool to see that other games look at brink for some inspiration : D
