I've a mod with similar changes myself, and like what you've done overall. Some comments:

Basic Satyrs:
8 gold cost and staffs makes them alot better. I like the natural protection 2. The javelin throwing ones might be too good for 8 gold. Perhaps lower their precision?

Satyr Veterans:
They need better morale. I'd actually just take them out, and let a veteran satyr be one with one star.

Satyr Hoplites:
The strategic move 2 is a good idea. IMHO they should also have round shields, else why call them Hoplites? This makes the Hoplites quite good, perhaps enough to raise their cost 1 or 2.

Satyr Champions:
Way too good with Thorn Staffs (although I like the idea); The old Revelers really did suck though. I like the standard effect, though I'm not sure about trading Berserk for Skill.

What about taking the Original Revelers, and adding standard +10, a snake staff, and javelins? This would make them usefull in small numbers, which seems about right.

You need the javelins, otherwise you won't mix them with Javelin Satyrs. Ctis' snake staff retains the flavor you were after, but don't come with +2 attack/defense; just refer to them as thorn staffs in the description.

Oh, and I like the name "Reveler" much better than "Champion".

Centaurs:
Bugfixing their natural protection to 3 is good. I don't think the standard on the Centaur Commander fits however.


Some other thoughts.
The Dryad/Hierophant change you commented out of your mod is interesting, and would improve Pangaea quite a bit. I'd raise the dryads costs to 90 though.
