Gotta love the player that shows up at the table with 20, 18, 18, 17, 16, 15 stats and max hp. I always make my players roll their stats in the open at session zero.
I was in a 5e game that used the average HPs. I was playing a high-CON tanky paladin. Then it came up that the rogue had significantly more HPs than I did. They said they misunderstood and was rolling. The DM just let them adjust.
Then we checked the math and they couldn't have had that many HPs even if they rolled max every level. More than a little bit sus.
This is partly why I always insist on standard array / standard point buy for stats and fixed hit points. No rolling. Not only is it too tempting to cheat, but it also provides too much variance among the PCs. I prefer everyone to be on equal footing.
