Sure, 30 can work, 40 would just be my preference. shrugA cap of 30 is fine. It's just that in the 5e MM, the cap is more like 19, with only exceptional monsters ever having 20 or greater. This means monsters have a crapton of hit points just to survive. I think there is also an issue with ability score mods + point-buy + ASI. The hit die range is pretty huge, as low as d6 for the wizard, and as high as d12+5 for the barbarian. And of course, multiattacking characters typically are adding a flat +5 to +9 damage per attack, which adds up.
As I've said before, it is an easy fix, and something we do in my online game:
- All AC is +4 (or +5 if you want...)
- All HP is half
- PCs get CON bonus at level 1, and then just HD until level 10, then just a static bonus (+1 to +4) for levels 11-20.
- Everything is proficient in all saves. If you already had a proficient save, you gain advantage instead.
FWIW, as is, the typical hit probability is actually 65% across all levels (+/- 5%). With extra attack, the chance of scoring at least one hit is about 87%. Way too high, IMO, and it makes the game boring, slow, and tedious.

This was something I considered before just deciding on a flat +4-5 AC bump. But you make a great point and I might revisit the idea.f proficiency bonuses were part of AC calculations, the result would be really both really flat (you'd pretty much track 1-to-1 against on-level enemies) but the variance would be a little higher (goblins would stop being able to reliable hit you but level 13-ish).

It would all be adjusted to compensate for the greater range of course. Like others, I don't want to return to 3E and +40 or more on an attack roll, but I like the idea of 40 cap since the d20 is half that. It means, at maximum, the die roll can at most count half of the result instead or more than half. With a 30 cap, the d20 swinginess is felt a lot more IMO.Oh hell no. If you've got a 20th-level fighter with a +3 sword, they still only have a 25% chance to hit AC 30. Any higher than that and you might as well just declare the monster immune to physical damage and not waste the players' time rolling.
Yeah, it is terrible when it comes to skills! Which is why (for skills) a lot of tables change to either a 2d10 or 3d6 roll, so the curve is re-introduced into the equation.Skills load everything onto that one d20 roll. Because of that, bounded accuracy dramatically limits a skilled character's ability to shine in their particular area. The uneducated barbarian has a decent chance to know stuff about Arcana that the wizard does not.
Even there, however, I don't think relaxing bounded accuracy limits is a great idea. I'd rather see additional elements introduced to the skill system to benefit the skilled PC. One possibility would be to bring back 3E's distinction between "trained" and "untrained" uses of a skill: Certain uses of the skill simply require proficiency, and can't be done at all if you aren't proficient.
This is the debate IMO. 5E treats ability scores as not just natural talent, but also a limited amount of training or exposure, and the swinginess of the d20 compared to the cap 30 adds in the other random elements (such as the barbarian growing up near crystal caves).For instance, if they're examining a magical crystal, perhaps the Wizard did not study the crystal in their life but the Barbarian remembers growing up near a cave where there existed such a crystal. Therefore, a barbarian would understand a crystal more.
The problem with relying on the swinginess of the d20 is unless you track your successes and how you account for them (without having actual proficiency), the next time you roll for something similar or even the same subject, the roll could go the other way and you know nothing or fail, etc.
It creates too much inconsistency for me, but I know the designers wanted to favor as simply a system as they could while allowing for some decision points. In that respect, they succeeded, but personally I am not thrilled with the results.
