(Note session 0 must always have an Alignment discussion with the DM being the final ruler in what is good and evil.)
What happens when you totally drop alignment? Not much. DM will just quit asking why the PCs burned down the orphanage because Little Ricky kicked the Paladin in the ankle.
Adventure League will have to come up with a rule which covers Evil actions but without using Alignment. Heck, two or more of my PCs were Lawful Evil in my Icewind Dale campaign. The only official thing I could do was change their alignment to evil and banish their PC from the campaign. But during Season 9 the AL team stated you can change non Mechanical stuff between sessions. So hair color, sex, eye color, height, alignment, weight, and sports team could change. So Bob would just write lawful good on his pc sheet in dry erase.
Spells would have some descriptions. Protection from good would Protection from Non Material. ETC.
I think 5E has hit the sweet spot on the Alignment. I think the monster manual needs a bold edit. Change ...The alignment specified in a monster’s stat block is the default. Feel free to depart from it and change a monster’s alignment to suit the needs of your campaign.....
To "THE ALIGMENT SPECIFIED IN A MONSTER'S STAT BLOCK IS A SUGGESTION ONLY." Yes bold it. And some of the more RAW people here can then start quoting and paging the Monster manual.
In the MM they already have: "The alignment specified in a monster’s stat block is the default." Unfortunately it's just buried in the intro. IMHO It should be it's own section in the DMG and spelled out more clearly in the MM.
Unfortunately it looks like their stripping it even from individuals in the new books which to me is an over-reaction. For example I was just browsing Van Richten's guide and there are no alignments for the darklords. Now I have to read paragraphs of text to understand them. If I had alignment, it helps me set the tone for them. As the MM says "A monster’s alignment provides a clue to its disposition and how it behaves in a roleplaying or combat situation."
They still make it clear that these entries are about very bad people. Nothing has changed in how they are described, but they've taken away a simple tool that helps me understand them just a little better.
