They dont change Bless and Curse beacause you have the abilities and gear to deal with the combat mechanics in most encounters.Only one or two are really tough and you need to nuke source skills and fast.
I played a lot of Divinity Sin 2 to be able to play tactician as normal..The combat system could be better but i guess the devs are learning as all of us do from feedback and mistakes.
It is a good game though and game of the year by far.
