D&D 5E (2014) [House Rule] Dropping proficiency bonus

[Horwath]

Interesting!
Where do you use this rule?
It also allows for more natural ones, if that effects what you're using it for. (8.3% for crits/1s instead of 5%, for folks who don't want to look it up.)

if agreed on, for everything.
natural 1 is either ignored or counted as "-5" on die roll if everyone just "needs" crit failure.
and there is crit success only for attacks, nothing else;
1+11 = 6+6 = 12+0
