OP your story simply doesent add up. First of all you already admit that you dont know the rules. Yet you want to make a massive overhaul to these rules that completly negates about half of the class features, spells and abilities that are in the game.

Its not about 'not adding more choice' but rather its about the fact that you fundementaly do not know what you are talking about. Maybe read up on the rules before you make suggestions to change parts of them.

And its nice that you passed the game without dying once. Seems legit. Considering the encounters amd rng in tje game pardon me if I press X to doubt that fact 😂
