70% is the Sweet, ain't it?

First Post
I read somewhere that the computer game industry has made studies that reveal the human mind loves a 70% success rate. Let's discuss how this will influence the design of 4E (assuming the designers will aim for this particular success rate).

A first level fighter often have AC in the low twenties in 3E. But the same fighter will probably have something like +5 on it's attack. This gives the player a mere 15-25% chance of hitting with a common attack. First level ain't sweet - and we already know this.

In order to have a 70% chance of hitting in 4E something must be done about AC, or BAB, or both. We know that AC will be removed in favor of defenses. I'll hazard a guess that a fighter will have a Ref Def of about 4 points lower than his to hit bonus. I.e. a fighter with a +5 to hit bonus at first level will have a Ref Def of about +1 (+10). The equivalent of AC 11.

I'm also guessing that armor will be sub-optimal compared to innate Ref Def because armor is so good at low levels (in 3E) but this problem will go away as the level based Ref Def increases. This means we won't see plate mail +8. Armor will be toned down to something in the range of +1 -- +5 at the very most. -Otherwise you ruin the sweet spot.

Does this make sense? Will anyone care to make further predictions based on this assumption?

Consider the following table:

Level --- To hit --- Ref Def
1 --- +5 --- +1
2 --- +6 --- +2
3 --- +7 --- +3
4 --- +8 --- +4
5 --- +9 --- +5
6 --- +10 --- +6

At this rate armor will be a wrench in the machinery for a long time (if plate remains a +8). I think it's safe to say you can use armor or Ref Def as your defense, as it stands in SWSE. If armor only reaches up to +5 heroes will stop using them pretty early whilst common NPCs will still be wearing them (as common NPCs are supposed to be low level dudes in D&D).

The table above is probably the progression we will see for warlords, clerics, paladins, rogues, and rangers. Fighters will have a slightly better To hit (an extra +1 or even +2 in rare circumstances). The rest of the classes will lag a few points behind. But they will keep up and not drop further behind as is the case in 1st through 3E.

I'm sure you are wrong. The system will be made so that paladins, cleric and fighter will still wear heavy armor whatever their level, while ranger and rogue will have light armor and wizards or sorcerer will have no armor.
This is just a bet.

They have the option of adding armor to Ref Def but the spread for doing so is limited. It might only hold a +1 -- +3 spread. -Which does correspond nicely to light, medium, and heavy armor. It could just work as there are only a few viable armors in the PHB right now anyway.

Still - do you believe 70% is sweet?
 

Sorry, but how on earth do you get a fighter with a 20+ AC at first level?

I do agree the with the basic premise of your post, in fact I'm working off a similar premise for my current "3.75" homebrew.
 

Interesting. I hope WotC uses information like this.

A 1st level fighter wouldn't have an AC in the low 20s though, and neither would his opponents. He has scale mail and maybe a shield for an AC (with dex 13) of 15 or 17. He's fighting goblins, orcs, gnolls which have AC 13-15, so he's hitting roughly 50% of the time.

Of course, it isn't the Fighters who really suffer at first level. If you're a Wizard, you've got a couple decent spells, then you have to try to hit enemies with a crossbow, with maybe a +2 bonus.

Errrrr... no, not at all. 18 is exceptionally high for a 3E fighter. +9 is the absolute maximum combined armor + dex bonus possible (not counting padded armor/no armor, because no ECL 1 character can have more than +5 dex), and that requires full plate armor which is too expensive by a factor of 10 for a 1st level character. Breastplates, Chainmail, and all the heavy armors are too expensive for 1st level characters to buy using the default rules. That limits us to Scale Mail/Hide (+7 total armor/dex) or a Chain Shirt (+8 total armor/dex) and a heavy shield (+2 AC) for an absolute maximum of 20. That 20 requires that the character to have an 18 Dexterity, and even the scale mail requires a 16 Dex.

Not gonna happen in the vast majority of cases. Certainly not enough to qualify as "often".

I was wondering the same thing. I think the average I've seen has been 15-17 for a Fighter 1.

70% does sound like a comfortable success rate, though.

Human Fighter 1 with Scale Mail and Tower Shield and a Dex of 14. 80gp.

Edit: Fighters get Tower Shield Prof for free.

Reference? I've never heard that. (And I read Game Developer every month.)
