I must say, Nat 20 Crits in 5e is one of the rules I'm not a huge fan of. When players score a natural 20 they want and expect to do massive damage. Any low roll sucks.
One homebrew is max damage every time instead of added die. So, Crit with 1d12 = 12 plus bonuses. That, at least beats rolling 2d12 and rolling 1's.
I like max normal die + extra dice rolled. So 1d12 Crit would be 12+1d12, so at least a minimum 13+ bonuses. That's for players. Enemies get standard rules, because the players are heroes. They get perks.
