The issue isn't the damage spells.
It's the shenanigans spells and the suck spells.
If you have 7 big spells and you have 7 fights, you can cast 1 per fight and go down to Cantrips and SR features. Maybe you hold back and save 1 more spell for the boss. Or you cast a definitive or utility...
Guys, we don't have to take away long rests.
I'm just suggesting that a 9th level Wizards slots don't look like 4/3/3/3/1 + X
That's 7 good spells. Seven spells of 3rd level or greater at level 9. Seven
And every full caster in the party has this. All of them with seven high power spells...
Short Rest were never the problem.

In 2025 today, the community wanted all 10 of 4e fixes (playtested better of course).
That's the fundamental problem that D&D has. Everybody knows what the issue is when it comes to bosses. The problem is that...
Nope.
The whole system wasn't a bad idea. It was just to drastic a shift.
If 4e Essentials were the original idea, it would have been loved. The issue was that Essentials came too late. The people who like 4e didn't need it. And the people who would have liked Essential had already abandoned...
