This is what I do. Maybe that makes me a wimpy Dm, but I just don't want the barbarian rolling 1's and having fewer hp than the wizard.
Heh. It is not wimpy IMHO. More hit points means more resilience and I apply the concept to NPCs and monster too. The HP in the MM are also the just the minimum and are usually higher than the default. Monsters in my campaigns can also spend their hit dice to heal during a short rest like PCs can.
