On a side note: why so many people take for granted that video players that approach this game now about DnD and its mechanics?
Larian needs to do a much better job of explaining how things work, regardless of what system is used. That said, if this game is being sold as a D&D game, it makes sense that folks who are familiar with D&D already should be able to pick things up quickly (which is currently a little bit true, but is hindered by the numerous places in which they have diverged from the D&D ruleset).
