Rather than having to commit totally to one vision of the 5e rules, maybe we can have both?

Loose 5E mode: 5E is used as a base template and then tweaked to make for a more fluid and actiony game with crazy surfaces and bonus actions for everything and so on.

Strict 5E mode: The game follows 5E and may feel slower or less engaging to some players as many characters will have very simple turns often.

Let people play how they want *shrug*
