of course i missed a lot, if i write everything then the whole page will be filled :p
we've played dwarves 2 ages ago (not full dwarf luckily) and we've warred with good dwarf kingdoms, we know their weaknesses and how serious they are. its actually a very common mistake, many many ppl underestimated dwarf thievery penalty and many top kds chose dwarf that age and all regretted it. and most likely they wont make the same mistake again (at least for the real top kingdoms)
as for fog, its not exactly a new thing, various races had it for a long time and ppl know how to deal with it
