I love this game a lot, and I saw countless videos about this game throughout my life. I love to play as the engineer, since I like to support my team and because I dont have to aim (my computer lags when enemies come on screen). One suggestion I would like to give is to nerf sniper, spy, and pyro at least a little bit, since they seem to be incredibly powerful classes and give me huge problems. Overall, 8/10.

As long as you know how to do them then its just practice from then on. The more you do them the better you will get at predicting where people will be so in short just keep practicing and dont give up!
