I am going to fudge a bit and go with a bakers dozen of mine
#1- Varient classes (channeler, dark channeler, elemental channeler, woodsman, martial artist, adventurer)
#2- Feat swapping for background basically regional class varients
#3- Bonus spells known for sorcerers
#4- Point buy for character building
#5- Regional Feats and Skills
#6- Automatic "good+" hit point rolls
#7- Defense rolls to determine AC (roll+armor+class+mods) of 2d10 or take 10 players choice
#8- Greatly improved shields
#9- Optionally used wound point system
#10- Level based bonus to AC
#11- A rule I saw online, Arcane failure chance reduced by a Bards perform skill
#12- Prestige classes are either custom for the game or better arenot used at all
#13- Brownie points for roleplaying. Use em to boost rolls and perform whimsical stuff.
