I'm defensive because you called me out as "coming to sugar coat it" and put me in a position where I had to defend myself. Let me be clear:



Open Plan and Closed Plan dungeons are supposed to be equally valid/viable. Right now it does appear that open plan is a little stronger at the moment so yes something needs to do.



But as someone who talks to the dev team on a (mostly) daily basis, and can therefore say with absolute certainty that the costs of defensive tools are being discussed now (i'm part of the discussion as it happens), we are trying to restore the balance so either type of dungeon is viable.



But adding wall props is definitely not the solution as an extra prop would mean an extra minion spawning, meaning the closed plan dungeons would have more minions than a open plan one, leading to imbalance in the other direction. Similarly with room efficiency, we could do it sure, but it's either an incredibly powerful modifier which makes a noticable impact (i.e sins researching at double rate and defense parts being made twice as quick) which is obviously OP in terms of balance, or it's a tiny modifier that only increases the impact a little, and is therefore practically invisible, most players wouldn't see/know about it.. making it almost completely pointless in the first place.



We do need a solution to make the 2 choices equally valid, i'm just not sure either of the ones mentioned so far as it. Especially as the issue goes deeper than just walls vs no walls. But again that's something we're discussing internally.
