I'm not really a big fan of adding MK:Tour tracks to Deluxe. The design of the tracks is starkly different than the original ones brought over from 8 which makes them far less satisfying to play on.
Don't get me wrong, I guess new content is better than nothing, especially for a game as old as MK8, but I miss the old days of online multiplayer where the smaller pool of tracks were way stronger in quality.
