Also the patterns syncing with the music rhythm and tempo, in box classes, is the worst in the metal/rock songs currently in the game (base ones, not the DLC packs, didn't try those yet).

I know this genre is a bit more difficult to do this with, but while some songs or parts of songs are quite ok, on others the sync with the punch drones is completely off and it gets very strenuous on the player, since you try to keep the groove once you get into it.

While I am a metalhead, I started preferring other music genres in fitXR due to the discomfort caused by this. For example, most rock/metal songs in Beat Saber (stock ones) do not suffer from this, you can always groove along your playing just fine. :-)
