the thing with the steady aim rule (at least in it's no long range penalty incarnation) is that it essentially allows you to field up to 8 guys who hit on mostly 3's and 4's the entire game from any range, which is fine in a larger scale game but strikes me as ridiculously deadly in a game like mordheim.
i realize that i have very little basis for comparison, so i looked up the thunderer stats in the treasure hunter warband:
0-5 M3 WS4 BS 3 S3 T4 W1 I2 A1 Ld9 for 40 GC.
a crossbow is 25 GC and a handgun is 35 (i have no idea what longbows actually cost. 15?), and none of the dwarf special rules pertain to shooting. so that's 65 - 75 gc for a way way way less accurate shooter (but with s4), although it's more survivable and whatnot.
a marksman with a longbow is 40 gold, but has bs3 and suffers all shooting penalties. that said, you can also take 7 of them.
i don't know... i guess i just feel like those shooting penalties are there for a reason. again i don't have the greatest grasp of other lists or playtesting or anything, though.
i also like the traps thing. you can always tweak it a bit to make it more your own.
yeah that reikland shooting rule looks insane. maybe i'm just paranoid because i've only ever played one warhammer game in which i ever had a decent shooting unit?
