I think the main problem with this current update, is that everything is either way to strong in the beginning of the game, or everything is way to expensive despite being essential to your dungeon. The biggest offender of this is the research cost, you get so little research and yet you're supposed to have it in the triple to quadruple digits to get essential tech unlocked, early game it's damn near impossible with the constant raids and sometimes your own minions dying to their wounds not being treated, because the infirmary cost 200 research to unlock while only getting 15 per day. If the devs fix this major issue at hand it could a tremendous amount to help avoid early deaths and game overs.
