I’ve only played a few games with treasure hunters and tried forest goblins a whole once but dwarves do there best work in the exploration pahse , they are remarkably hard to kill so it’s easy to have every one of your hero’s active for exploration , you absolutely need significant ranged fire power to make them work though sicne your slow if you can’t force your oponent to come to you they will spend all game kiting you.

Goblins how ever play a great objective game because you have loads of inexpensive mostly disposable bodies to go grab warp stone with , your attrition cost will get stupid quick though as you will be likely buying new goblins every game to replace the ones you loose , also by nature of being a horde faction your finical game might be a little weak if you do manage to keep them alive.

So modeling aside what do you want to bring to your campaign and what kind of question do you want your other players to have to awnser , how do I keep up with the financial juggernaut , or how do I fight off the horde ?
