Not really.
They completely rewrote large sections of the rules going from 3e to 3.5. Compare the initiative rules, for example. The classes often worked considerably differently. It wasn't just shifting the same powers or two up or down a level, it was fundamental changes to the basic framework of the game. For example, the Ranger going from 3e to 3.5:
Just about every aspect of the ranger changed.
- HD from d10 to d8
- skills from 4 to 6 per level
- two "paths" to pursue gained at levels 2, 6, and 11 (no TWF at level 1 anymore)
- TWF: TWF, Imp. TWF, Greater TWF
- Archery: Rapid shot, Manyshot, Imp Precise shot
- Favored Enemy is completely different
- bonus is +2 at each level now
- damage affects those immune to crits
- every 5 levels, you get +2 to a new enemy and +2 to an existing one
- spell list changed (no polymorph self, add in barkskin and commune with nature)
- free endurance feat
- swift tracking
- woodland stride (re: druids)
- evasion
- Hide in Plain Sight (in the forest), Camoflage (hide in woodland setting without concealment)
Wild Empathy is no longer a skill; it's a class feature. The bonus is simply "ranger level + Charisma modifier".
It's no longer as front-loaded and has enough abilities that I can't picture leaving it before 13th-level (when you get Camouflage).
Animal companions have gone from being worthless to just being sucky.
And that's the changes to ONE class. Never minding that virtually every class got the same level of reworking going from 3e to 3.5.
What changes in 2024 compares to that?
