All I can say is I completely agree with this, this could really make the challenging fights stand out as more sort of "boss fights" against important enemies so you have to properly prepare. However the early soldiers you fight in-game and all that can only figure out the basic stuff like lighting fire where there's oil and putting out fire with water.
I also noticed that the enemies don't use grenades very much (especially compared to DOS 1 so that could be added to make them less rare and allows for the character to use them more as well). Smarter enemies can use more grenades as well.
At the moment every fight is challenging which makes it extremely fun but also kinda tiring, I want to be able to relax a little while fighting some of these groups of enemies but also be even more careful and tense when fighting hard enemies. At the moment the feeling is all the same no matter which enemy it is. I really want to add the idea of a boss fight to the game instead of the usual "This is a hard fight just cause there a lot of enemies". The only things that come close to a boss fight (Still haven't finished it) but still doesn't quite satisfy the term is the queen fire slug and Migo. I mean the main magister building was all a bit boring as all enemies had the same health and dealt the same damage. As they all say "Quality is over quantity (but if we can have both that's even better)".
