kaffis, fickegreendice, and tunewalker make great points. In my opinion FFG has done pretty good with the synergy of named category, and appreciate the direction the game is headed. Also, I don’t think Seventh Sister or just any other character should be able to maximize one of the best if not the best weapon in the game as well as Maul himself just because they’re blue.
From what I understand we have this nerf to Maul’s lightsaber mainly in response to slow down the “OTK” decks. Correctly limiting an upgrade’s full power potential to their named characters could be a way to keep cards of these types in check, and give other future higher costed characters more value.
Maybe I’m bias in my thinking because I think the main (e.g Luke and Vader) characters that have the supporting facts to back up a character’s capabilities or power usually (not always) should be In the best decks with the best pairings. Not saying anyone is wrong or that other characters shouldn’t be able to shine either.
