It's true that win streaks don't tell the whole picture alone, I only brought it up to maybe help others who care about it.
Win percentage would be the most meaningful stat, but it's understandable why it isn't shown. How disheartening would it be for players who have hard a time beating dungeons?
I don't know maybe something simple like changing skips to -5 points instead of the score reset would be nice. Makes single missed dailies tolerable, while taxing overcautous players heavily.
