First of all I've played through all ac games.
I wish the combat resembled the combo system in brotherhood, I wish the parkor resembled unity, I wish the world was lived-in like syndicate. Mirage brings nothing new to the series and the characters are dull and generic. The graphics are great. Back to their roots? Hmm, not really. If you wanted to take this game back to it's roots, you should have reintroduced low profile actions and high profile actions. Overall it is a meh game, not great. Keep trying ubisoft. Ezio is still goated and the most accomplished assassin.
