The Crimson Binome

I'm not sure how long you've been DMing, but if you play to high levels (and especially if you don't use feats), you may notice that every barbarian has exactly 20 Strength and every warlock has exactly 20 Charisma. The alternative is that some characters would just be objectively less powerful and less useful than some other characters, and that's not very much fun for most people.I am almost always on the DM side of the screen but I have noticed something common to almost al PC's. They have a 16 or better, usually better, in their main attack stat. This is true regardless of the method for character generation. I don't know why it bothers me or if it should but when every scorcerer is charismatic, every wizard intelligent every, rogue nimble and every barbarian strong and always within a 4 point threshold it messes with my chi (eg. qi).
For as long as stats have been important (since at least 3E), players have been doing their best to maximize their prime stat. The only difference with 5E is that now they cap everything out at 20, so wizards are able to develop their other stats eventually, instead of being compelled to improve only their Int forever.
