But that's the point - that's not what's happened with 5E.
5E is
significantly easier than any edition I've come across to break. 5E looks and feels
significantly easier than either d20 or 4E.
So this is not the whole truth.
I am fully prepared to tweak encounters to match the performance of my players.
What I do not accept is when the encounters are essentially useless as written, as if meant for a party five or even ten levels lower, and in need to be completely rewritten from scratch.
And just as a reminder, now we're definitely not talking about the Death Knight encounter. Now we're talking about the level of challenge offered by the latter half of Out of the Abyss, to pick an immediate example. This was what made @
Celtavian quit 5E after all.
But it's not confined to one adventure module. One inexperienced or naive module more or less is nothing. We can all live with that. What is so worrying is the entire Monster Manual, and how it appears to be written by staff with no real experience of high level hero capabilities. The way ranged fire is made "cool" with little thought on how this impacts the overall game and indeed the fundamental assumptions of the entire genre. How Greatweapon Master interacts with commonplace class features of the PHB. Indeed even the utterly basic things: the atrocious index, and the completely inept way spells are categorized.
5E is great, no dooubt about it.
But that's just it. Precisely because it is so well designed in general does the flaws and niggles stand out, especially since they're so worryingly indicative of not having learnt by past mistakes.
