Not sure what you mean be 'experimenting'. Githyanki is already a race in 5E. Vampire spawn as well. Werebear is a CR5 creature so that's not going to be an option.
True...
I see there is a lot of cool enhancements already in this game...I guess it was just a mix of expectations and nostalgia.
Hopefully it will be cool to play with both PC and pre-made characters..
