Have you looked at pathfinder PF2?
I did and though I really like it, it becomes bloated beyond 10th level. Especially the rogue.^^Have you looked at pathfinder PF2?
That being said, allowing advantage and disadvantage to track separately would be a very easy house rule, one I use myself.I don't think you are missing anything here. There are going to be moments during game play where you have both an Advantage (ex. you and a fellow party member are flanking an opponent) and a Disadvantage at the same time. Advantage and Disadvantage are pretty situational, and you're more likely to get one or the other rather than both.
