I finished the game once, have 2 co-op games running with friends, and just started a modded playthrough where the whole party is Artificers. I highly recommend giving some of the mods a try once you’ve played through vanilla. They’re super easy to install and add so much fun an variety.

I don’t think so - I’ve been playing since early access and you can block doors, it just usually takes 2 people to do so.

Putting Jump on a bonus action basically fills the role of tumbling through enemy (and ally) spaces.

Yeah, if I post something here, I’m posting it because I want other people to see it. That’s kinda the whole point of reddit-style social media.
