What if each race got it's own Racial Class Skill?
No matter what the class this skill would be considered a class skill and if said class already has skill goes from 1 per lvl to 1.5 per lvl.
Drow = UMD - A lot more people suddenly playing drow.
Elf = Balance - Elves are meant to be lithe and graceful are they not?
Half Elf = Bluff - From the Half Elf bonus feat - Diplo and intim don't work in my mind for the flavour.
Human = Swim - No other skill makes sense for humans.
Half Orc = Intimidate - Pretty obvious choice here.
Dwarf = Concentration - Stubborn Bull Headed Dwarves tend to be hard to distract.
Halfling = Tumble - Maybe Heal, Move Silently or Hide - Tumble has the most use for all classes though
Warforged = Repair - Make High enough repair skill = Regen 1hp/1min.
These would be my choices of course.
The idea stems from Drow's natural magical affinity - Figured If drow were to get a buff the other races should likewise.
