And we do Crits as you get max damage on your regular damage dice but roll for extra damage. Otherwise Crits feel nerfed a lot of times. My wife would swing a greataxe and Crit someone. "Yeah! Crit! Die orc!"
Rolls a total of 10 with 4d6+4. Wha wha! But if a crit does 16 + 2d6... Now it's like HECK YEAH! A CRIT! That may not be RAW, but it's a lot less disappointing for players.
That's exactly how we do it when I play table top. We were tired of crits that did less damage than an acutual regular attack
