So when there is a requirement to hit a dc of 20 it shouldn't be a natural 20 all the time, if the character has bonuses to the roll.
My example using pick pockets - trying to steal an item from the vendor and the target # is a 20.
d20 rolled is a 17 + 3 for prof, + 4 for shape change ring, +4 for dex = 28.
Yet I fail a dc check of 20? this should not be a natural 20. if that's the case there's no point to bonuses or a dc check, even had a dc check of 30 - with bonuses can be hit.
So why do players get punished for having to roll natural 20s all the time when bonuses would hit or exceed and that's the point of bonuses..
