Well, we are in EA to test things, aren't we? They have this opportunity to try different options with us, the 1 million+ EA buyers.
Yes, but starting with options does not change the requirement to develop, test, support, and balance those options. I think a better way to test what works and what does not is to go back to starting with the 5e ruleset fairly closely, and then seeing what works and what doesn't, and then you can find the places where tweaking rules can be fun.
Right now there are so many changes to gameplay which are all connected and have effects which affect other things that they can't change things piecemeal.
