Looking at some of the racial modifiers, they did not seem to jive with the description of the race. The changes I think should be made are as follows:
Dwarf: +2 CON, +2 WIS, -2 DEX
Gnome: +2 DEX, +2 CHA, -2 STR
Half-Orc: +2 STR, +2 CON, -2 INT
Dwarves with there stout build would seem to be less agile than the baseline. I am also opposed to negative charisma modifiers as sheer force of personality should not be race dependenet.
Gnomes, owing to there closeness to the fey, should be less hardy and more agile. Dumping the Con bonus also helps bring the gnome in line with the frail races as listed in the starting hit point side bar.
Half-Orcs, while they may be cunning and wily, they may lack in common sense thus negating a Wisdom bonus. To me they are stronger and more durable than the baseline and the modifiers should reflect that.
Talk amongst yourselves.
