Same. I don't think of 3e as an extension of 2e because 3e added a lot more complexity and numbers bloat went out of control. Which is weird for me to say, because 3e seems like the very obvious extension of 2e's Skills and Powers lol.
Specialty priests, spell schools, thief skill progression, and non-weapon proficiencies being d20 roll under your stat are all things I really liked. I still like d20 roll under ability over skill point progression (3e and up) because lower levels PCs were competent if they had a really good score. The basis of success was more of how much talent you had in one ability rather than how experienced you were.
"Oh, you have an 18 INT and need to make a history check of something you read when you were studying? You're level 1 so your total bonus is +6. Even though you read that topic more recently than the 20th level dude with a lower Intelligence, they still have a higher bonus to recall it because they spent more time lobbing fireballs and gaining XP."
100% agreed.
