Awesome, ya I think I've got a plan for the specials. Chainsaw from Space Ork kit, done. Stickbombs on gobbo model, done. green stuff a simple coil on one end of a spear, done. I could always just buy a fanatic blister. So that just leaves the trolls. So I suppose I should keep an eye out for older models then. It makes sense that the newer ones would have increased in scale.
Awesome thanks for the tips. Ya, I hear Goblins are no doubt fun but are impossible to win decisively. Sounds like my kinda team!
