Battlefield 2 TKs are fucking lame

I put C4 on an enemy tank, someone blows it and me up, and I get negative points for it. I don't know what the fuck DICE is smoking. Oh here's another one... after you lay out all your C4 packs, guess what? It automatically switches to your detonator. Click too many times? BOOOM! in your face. It's such a good game but this crap annoys the fuck out of me.
