I've seen a truly daft and overpowered bug today. I was in a panzer tank, fully upgraded and 100 health. Support guy runs upto me, throws a mine which lands next to me and then shoots it. Instantly destroyed me. I've had this happen twice more on different games by different people and its absolutely ridiculous. If I drove over a mine, sure, yet I didn't and they go off like small nukes. The dynamite doesn't do anywhere near that damage to vehicles and this definitely needs patching sooner rather than later.
The changes to the M1A1 are a joke too. Literally useless now that it takes 8 rounds to kill someone even at close range.
