He talks about 'pyro blowing up in your face'-probability because of oil and poison surfaces, wich can make it pretty deadly under certain circumstances. Some worry about that stuff more than others.
You could replace sneaking with +2 on const or somekind of buff while drunk, because dwarves like to trink a lot? Or +1 loremaster because they are good with equipment or +1 bartering because they good with gold and very persistent while trading. Or +1 max ap because of high stamina. Honestly dwarves are small, but you do not expect them to be that light footed.
