Currently game calculates a skill check DC in background and shows us what we have to roll on the dice. This means same task have a different target for your different characters.
Normally on DnD you add your bonuses up and you try to beat DC. DM does not gave you pre-calculated "dice target".
There is a big reddit thread for this too; https://www.reddit.com/r/BaldursGat...iers_are_subtracted_from_the_dc_instead/
My opinion is , although it maybe easier for some / new players, it makes it harder to compare your characters, because you never see the addition of their skill focus. ( one has +5 , other has +12 for example) . Also, if these players got curious and wants to play 5e, they will be VERY confused. (5e is the simplest system, too simple for my taste but to unlearn something is very hard)
I suggest at least there should be an OPTION to show DC and Bonuses OR your d20 dice target. Since the math behind is very simple i believe it can be a representation option which make everyone happy.
