You know what, now that I actually see my gameplay after the fact, and with my body not flooded with adrenaline, I know how I can improve. Thanks, Intel.
The constantly calling for medic was because of the autocall plugin I had installed, it calls for a medic whenever I am low on health. I am going to disable that.
also, the thing at 6:33 on the second video was me trying to shoot, but my rocket launcher was refusing to reload

and that part where I would randomly freeze up, I accidentally kept hitting alt(which freezes the game completely), and I had no idea why I couldn't do anything until I hit alt by mistake again.
I would like to apologize for the pain in the ass I was, I am used to playing pub games and pub tactics don't work out well against organized clans like TSA.
