Had an awesome run today as Battle Engineer and Dead Ringer Spy.
I decided to try Battle Engie ever since I saw that video that Paradox put up yesterday, I had a lot of fun. I placed sentries in unusual spots then instantly moved away to help the others attack. Placing one right at the start of the round in the main room in Turbine proved to be very effective. I also placed Dispensers wherever my teammates were holding off the other team, it helped quite a lot. My main aim was to be as spontaneous and offensive as possible, and as a personal critic, I didn't do too bad for a first try. Of course, after this method began to work, half of our team went Engineer and held them off in the middle room, which totally threw off my buzz, it was for that reason as to why I then played as a Dead Ringer Spy.
The Dead Ringer is now officially my secret weapon for kicking ass in TF2. I've learned on the best times to feign death, and used that to my advantage. A protip: The best time to DR is when you're being attacked by a soldier/demo. The gib explosion death convinces them so well that you've been finished off. I also improved on learning on how to walk INTO rockets, stickies, and huntsman arrows. I got several combo stabs in, and in the end I added another 50 points to my score.
TL:DR - I was credit to team and here's my final score.
