And obsession with balance is worse than ignoring it. Too much balance makes for blandness and uniformity. Balance is just one tool, not an end unto itself.
That gives me very little faith in anything ENW puts out.
If Morrus means 4E levels of balance, then yes, I completely agree: its uniformness and blandness was its undoing.
5th edition is, at its core, wonderfully designed. Most if not all bugbears of 3rd edition are actually fixed, and not too many babies were thrown out with that bathwater.
And still, there are a few shining examples of "imbalance" made out to be strengths of the edition and not weaknesses. Such as magic items that actually feel magical again.
Or let's pick Fireball the spell for instance. Its eight damage dice make it clearly unbalanced at 5th level.
If that spell didn't exist and you or I added it to, say, a DMs Guild product, we would be shut down instantly,
and rightly so. Double standards? Perhaps. It is the
game's designers I trust enough to "break the rules". (Whom am I kidding? They can't break the rules! If they add a Fireball spell then that
becomes the rules!) That is why first-party support is so valuable for "player crunch", in particular class options and feats (the building bricks of a character).
What I would love is an alternate world where most 3PP was geared towards wonderful adventures, campaigns, and scenarios.
Your or my ideas for a story, a plot, or a dungeon are just as good as Mike Mearls' or Jeremy Crawford's. And the worst thing that could happen is the scenario leading the party into a fight they can't win (and even that might not be so bad); no systemic balance threatened.
I have had great use out of 3PP story and adventure material!
I just wish the customer base didn't crave 90% (99?) player options...
