I agree with this. The game would come closer to the tactical feel of 5e if these options were removed. Classes would also retain their unique personality. Wizards bring options to change the tide of battle with arcane spells. Fighters are dependable front liners who can take a hit and wield martial weapons with perfection. Clerics are devoted to their gods and have unique divine abilities. Etc. Etc.
Also take into account what it does to the identity of the player character. Are you playing the class you chose, or are you playing a mix of all classes.
