I was going to mention the feats that change crits in DnD 5E but I felt that was getting too far into the weeds. The fact of the matter is you skill doesn't really matter for crits in 5E. Maybe you decrease the requirment for a crit by 1, but let's say you have that and great weapon master. Shouldn't that -5 to hit effect your chance to crit? You're going all in on power, so you lose precision. Why are the odds exactly the same? It just doesn't make sense. The crit system is half baked and doesn't really work, and then your throw in advantage and disadvantage and the system is really flawed. Pathfinder 2E seems to have figure this all out, but the new version of DnD (5.5E, or whatever they call it) doesn't seem to try to fix it.
