Well I think I asked the wrong question. I was mostly thinking about offensive-defensive fighting styles. There are many situations (for example the last battle with the bishop) where you can feel that the designers of the game prepared the battlefield for an interesing fight. But if you don't fight there, just pull everyone out, and nuke them to hell then the whole thing is much easier (and boring). So don't you think that the game should somehow encourage or force the players to be offensive instead of just waiting at some gate and throwing any explosive/poison stuff at the exit? Like XCOM2, where the timer is forcing the player to do the boring defensive overwatch traps all the time.
