Would the modification dumb down the end game and reduce required skill or just make it different to result in less draws?
This is an interesting question. I think the modification (having a capturing king stop immediately after the final piece if it is a king) will make almost won or almost lost endgames a lot easier, but nearly drawn endgames a lot harder and interesting.
E.g. in regular draughts, you calculate endgames until you found a variation with a clear drawish position (given the piece counts and diagonals controlled), even sacrificing one or two men in the process. The stronger side has to check all these variations and the weaker side only has to find one that actually gives the draw. With the modfiied rules, you have to calculate more narrowly, because the side variations (where material is sacrificed) will lose quickly. The main variation however, goes on much deeper (you keep piece counts even as long as possible), and it requires a much more refined positional understanding to keep it that way.
I have done some careful endgame analysis of a particular draughts GM with almost flawless endgame technique in very simple 4 vs 4 positions. In regular draughts, he made draws in all 50 of those positions, and with the modified rules he would have won about 25 of them. It's a change very much in favor of the stronger player IMO. I view a drawing percentage as a "tax" on strong play. If the drawing percentage is X percent, then you effectively pay X percent tax on your advantage that you have over your opponent. In Stratego, X is very low fortunately
