That’s thin meat for roleplaying, and probably discouraging for the wizard who wants to be smart.

You still get to be smart most of the time due to where you put your points and proficiencies, but you're not all-knowing.

I like being consistently good at stuff.

But that makes you consistently middle of the road. The 1d20 still has that modifier to make you consistently good.

You used to be able to interrupt casters by getting up in their face. I see why they removed it- players don’t like it, too hard, losing your spell sucks- but it removed an important depth.

I don't like it for similar reasons. It's that thing where you said sometimes you miss, but I think it feels worse.

5e has vanishingly few ways of influencing the odds. No flanking. Expensive aid-another/teamwork. No situational bonuses. Few resources to dip into.

We play with +2 flanking rules. There are situational advantage rolls and such. Classes start with their resources quite early on.

You can defend someone else on their turn. Shit, I forgot, DND doesn’t even have this concept.

You can ready an action to trigger under certain conditions.

Some people like mayonnaise.

A ton of people like mayonnaise. I'm really not trying to pick a fight with you, and I appreciate this discussion, but you've been trying to say how bad mayonnaise is this whole time when I like mayonnaise, haha. At other times, I'll be interested in other condiments too, but mayonnaise is good on a lot of food, and it's easy to come by.
