In keeping with my trend to try and be proactive in supporting balance I'm going to start making demos of me doing the things that people complain the most about. My hope here is that at the very least, even if your overall skill at the game doesn't improve, you will be able to deal with me and my playing habits.
I give you me playing engineer on Turbine:

Powerlord is my real enemy for most of the game, however near the middle I vote scramble because it was just completely one sided and literally all it did was switch me (needs class balance scramble).
You will see me die several times and have my stuff blown up, but what most people have trouble with is keeping me from rebuilding or assuming that I'm not going to. This is one of the simplest strategies to counter. You see Powerlord do it a few times and a demo almost kill all my stuff once. You don't need a medic, but it really helps. I'm not really playing my best here, but I prefer this because it demonstrates that I can in fact be killed when doing this.
If there is no objection I also have some map design changes that would make this map more of a fight and less "lockdown the center and pick away at the enemy."
