I don't want prox chat. I already have to deal with too many people who just have music or whatever blaring through their mic. Or mouthbreathers, blech.
Grenades need to be opened up on the whole. Any class can use any gun! But grenades is where we draw the line! 40mm needs the same treatment. Assault should get smokes, support needs boom.
Spotting in this game is pure CoD trash level babysitting handholding. It needs to be heavily toned down.
I personally have no issues with vehicle spawn times. I have an issue with how many rockets engies get. And EA wonders why it's so hard to balance this part of the game. 2 engies have enough rockets to bomb all of Persia, yet somehow it's the tanks fault that they died.
