By the way DOS2 also has its own type of special arrows that you can use with your other attacks. Archers have a skill which works pretty much the same way as "dip" that we have right now. So at least half of the programming is there.
So, Larian, please. We know you can do it, you know you can do it. And you should do it, because otherwise those special arrows are going to become perfectly useless by the second third of the game. I'm already choosing special attacks over them more often than not.
