Still trying to wrap my head around the Great Hit Point Wars.
I guess we could dress it up a little by going all the way back to the early days of the game. One thing D&D did that some folks had trouble grokking was to make PCs more durable as they leveled. Their hps went up, and their saving throws got better. So a high-level character could survive being 'hit' by dozens of arrows, falling off a 100' cliff, or drinking gallons of poison. Criticism got pretty vicious, and some of the most celebrated non-D&D games of the early hobby very pointedly did not do anything similar.
In 1979, EGG published an extensive explanation of hps (and a less verbose one of saves) that tried to rationalize the mechanics. Some people shrugged and said 'OK,' and others shrugged and said 'no way,' and came up with other rationalizations. Neither official nor fan rationalizations really worked perfectly, though - most had serious issues with healing not be proportional, just for one example.
So, 2e ignore hps almost entirely, and 3e only hints at the AD&D explanation. So folks who have been using their own rationalizations, however weird baroque or unworkable get entrenched and forget the official version.
4e and 5e use something closer to, but like 3e much terser than, that old 1e AD&D rationalization.
4e had the edition war, and re-visiting the long-ignored issue of hps really not quite ever having made sense, became one of the many lame, contrived skirmishes of that shameful period of the game's history.
your not waiting, you got your answer Battlemaster +feat with maybe some bard refluff... that's it... now you can include the new rouge mastermind...
take 3 levels of rogue and 4 of fighter, take the inspire feat... boom your warlord...
If that's how you feel about it, I'll spot you only two months of the wait instead of half.
