That included removing the requirement that an essential Paladin is a Lawful Good. Then they added them back, but not wholly reducing their effect on mechanics. They first removed half of the alignments of 4E. Paladins are the most affected of any other class because no other class has an alignment that is so closely linked to their core function via codes of behavior. In the two previous versions, Wizards has partially messed with the alignment system because it frequently leads to arguments. The current Pathfinder GM phrased it as resembling that RAW is “an imperfect reproduction of the perfect game you have in your head.” That is a large one in terms of imperfections since it’s tied to an overall issue. However, sometimes RAW should be set aside to make way for Rule of Fun. Any light that burned within the heart of a paladin has been absorbed out. The 5E DMG defines an Oathbreaker Paladin according to: A paladin is an oathbreaker who violates their sacred oaths to pursue a dark motive or serve an evil power. Yes, but be mindful of how you define “Oathbreaker paladin in 5e dnd.” Rules in their written form are relatively explicit.
