D&D 5E - Tasha's Optional Class Features - Using Them or Not?

We chatted about it briefly and decided to use them. Since we're all on my DndBeyond account, I just turned everything on and told people to review their character sheets.

I didn't see anything particularly broken, and I'm not going to go through each and every feature. I figured that if it ends up being problematic we can always turn it off later.
