Couldn't we just make it easier and say if you have +5 in a skill, the minimum you can roll on a d20 is 5. This would allow all the trained people with +5 in a skill no chance to fail common things and people with +10 in a skill no chance to fail average things.That is all true, but still for me d20 has too much variability.
I.E.
if you are trained in a skill and have good score(16), that gives you +5 bonus to your skill check.
with d20 that gives you 5% chance for a very hard DC(25), with just basic training, maybe very hard DC should be unattainable?
but you can also fail DC 10(easy) 20% of the time, that is also little too much for someone trained.
If we go from d20+5 to d12+4+5(keeping save average and only one die roll, avoiding bell curve);
we get:
DC 25 goes from 5% to 0%
DC 20 goes from 30% to 17%
DC 15 goes from 55% to 58%
DC 10 goes from 80% to 100%
We could also just say if you have +5 you do not need to roll at all for simple things. This may get a bit off if all the PCs are rolling and the DM does not tell them the DC.
