Welcome to Librarium Online!
I recently got the Grimgor Ironhide model just to add a new model to my collection, but now a sudden urge to add him to my army has taken over my thoughts.
I simply ask the question: should Grimgor take part in the bloodshed?
For the Waaagh
Try him out in a battle or two to see if you like him. He is pretty brutal. the number of str7 attacks he (and strikes first) make him very formidible.
