I think the single largest flaw in Root is that players score abstract VPs that are no longer located on the board. This is a very poor model of a political conflict and it leads players to be inwardly focused. Instead of competing with others for space you can often all score your points for a round or more with almost no interaction. Additionally it means that there can be no approximate equilibriums, since almost all factions can never lose points and will be gaining at least a trickle.
For a supposedly deep diplomacy game it always cracks me up that a winning move is often so simple as crafting a card from hand or doing a mission as the Vagabond.
Andean Abyss by contrast (and probably the other COINs I haven't played) has the VPs as components on the board that others can interact with.
