Finally getting the hang of Demo and actually getting quite good with him in certain areas. Still haven't got the hang of his charge attack, but I'm digging the sticky bombs in payload maps. I really like hiding the bombs on the ceiling or walls, and just ambushing them when I see they started to move the cart. I'm still generally spamming grenades, but at least now I'm finding out good points to do it at so I'm netting a bunch of kills. Also finally unlocked the wrangler for the engineer, and after a round of playtime I can tell it's going to be a pretty awesome weapon.
Scout on the other hand is still useless to me. Maybe my computer can't keep up with his speed or something, but my bullets never seem to register. I've literally "meat shot" (or close to it) people multiple times, and they turn around and kill me in one hit. I know the scout isn't that weak since they've taken me out pretty quickly, I just feel like my computer is running too slow because of either the framerate or lag, so these shots are just grazing them even though it looks like I nailed a direct hit. It's fun to annoy people with the sandman though.
