Well, I guess I can be considered to be "experienced" with that list.
I played it during playtest, as well as during normal and event games.
win-loss ration is app 50% with a lot of draw-loss.
IF you play them with the Slayers as per the published rules, be warned that they are different!!
Miners will NEVER deploy near enough to the enemy to disrupt them straight on, also, no orders AFTER placing them.
Millitia and Minders suffer in armour for the 0cm shooting attack
Allowing you a squadron of Gyrocopters makes you loose the option to have guns and vv. so it will be a tactical descicion
The DragonSlayer is a cmd 6 <-- character, so the dwarf command structure suffers from taking this character and yes, he CAN explode, but those wounds are negated IF they dont kill the unit.
Try playing and post play(test) comment here ??
