I am glad we finally got some communication from the devs, i would be happier if we got it when the changes were released, but can't change that now.
I am glad they tuned down the PL scaling a bit, so we can actually kill smashers.
I think propanes are still a problem though, a single propane husk is enough to take down an entire tunnel in one shot if not upgraded, and even if you did, going in a tunnel to repair during a propane wave is impossible because they will just throw it at you and blow the tunnel up even more.
I think propanes should do less damage to structures.
If you neglect maintenance on your tunnels they will eventually fail that way, not like right now where your tunnels are just done for when you get propanes.
Thanks for the write up here, u/Rhamuk. I definitely appreciate the constructive feedback. We're going to keep looking into the changes that were made in the 11.30 update to see if / where further adjustments can be made. The tweaked down Propane damage is a solid suggestion.
