I am happy to see more faction, I think 4 is not sufficient for the long-term health of the game. 5-7 seems to be the sweet spot for most games.
However I am both shocked and slightly concerned to not only see new factions so soon but TWO in the same release.
However, it is understandable. While the new factions this early will dilute the amount of cards dedicated to existing factions, on the other side if you delay too long in releasing new factions they have too much to catch-up on.
I’ve worried but cautiously optimistic they can pull it off well. I’ve yet to be really disappointed in DTR thus far (except for the ongoing lack of wanted-punishment support, rawr!)
