Easy Dif = 5 which is a 75% chance of success if no skill Bonus at all Mod = 10, or 50% chance unskilled Challenging = 15, or 25% chance unskilled Grueling = 20, or 5% chance unskilled
DCs are based on unskilled characters.
So, Rogue unskilled at stealth would have to roll an 8 or higher for moderate stealth, which is 60% chance of success. Skilled would need 6, or 70%, and expert a 4 or 80% chance. With Advantage, say because of darkness, chance increases exponentially.
Moderate difficulty. Unskilled Rogue still needs 8, 60% chance, skilled needs 4, 80% chance and expert needs 0, 100% chance.
So, unskilled remained at 60%. Skilled increased by 10% and expert by 20%.
Take past D&D. Max skill rank was 4. Add +2 for Dex. So +6 for max Skilled at Level 1. Unskilled might be +2. Difficulty 15 is moderate.
13 or higher unskilled, 9 for Skilled. Unskilled = 35% chance, Skilled = 55%. That's pretty sucky for a Skilled character. Moderate means 50% chance for Skilled characters, not unskilled. So the entire system works fine as long as you're Skilled. Unskilled means it is brutal. Again, if you're an unskilled mage at athletics and you really need to make a jump... sorry. You're Doomed.
5e, the unskilled mage has at least a better chance. Certainly better than 35%.
That's what I like. Simple and better in terms of chance. Yes, Skilled people have a better chance, but it's not so big a gap that the unskilled is screwed.
In previous versions, a DC of 25 was impossible for unskilled, but many Skilled could do it well enough. It was too extreme and very frustrating. Skilled would be bored because they could ace it, and unskilled would just be poopmout of luck.
