It's true about monster criticals, but I think monsters that wield weapons might still crit. Criticals in 5e need a revamp, and I'm not talking about more nerfing, of all the common house rules to incorporate, adding critical skill checks, but not something like x2 damage is queer.
I can actually understand this a lot. I actually tend to cater Crits to who I'm playing with. If I'm playing with people who hate being wiped by a single hit - basically they don't want realism as much - no Crits for monsters. If I'm playing with people who like more fair Combat, then yes, monsters get Crits.
I equate it to difficulty settings in a video game. Crits for Normal mode done the RAW way and monsters too. Crits done homebrew for players and no Crits for enemies for Easy mode.
I also do variations where bosses crit but minions don't.
