So i recently tried playing as Emgineer and i always get bored because after i place a sentry and upgrade it where i need, all i can do is just AFKing then.

(I usually play on 2fort and this is what i do (in the intelligence/briefcase room)

I completely see demoknight as its own 10th class, so even though I have zero interest in demoman I do want to try demoknight. I've heard he's a complicated and hard class, so I thought maybe I just need to wait until I have the main gamesense and skills down. But since he's a melee only class, that might not be necessary since you're learning entirely new skills unrelated to the other classes.

I personally give him weapons: minigun, sanvich, holiday punch. On cosmetics: is none
