bastidThe counter to short circuit Engies is hitscan. Hitscan, flames, bison, will still destroy an Engie with the short circuit out. Pushes have to be approached with less of an explosive class mindset if the enemy is running it. Yeah it's "speeding up" in the literal sense of the word but a Concheror Heavy push I can see being pretty brutal. You can flash your Pyro to ensure he airblasts away the Engie so that he can't block shots on the combo with the SC, things like that. And through all this he has no Wrangler. Which is going to be huge no matter the weapon trade-off.
I'm more saying Demoman not being so dominant is interesting. I don't like stalemates either.
Just curious, do you have any hl experience? Because your ideas of ubering heavies in and pyros (to airblast an engineer away ?) are pretty ridiculous . I'm just trying to imagine a heavy push into 2nd point croissant, and how you think that would work.
