I have a shooty GK list that includes the VSG. I have received more complaints about that particular building that about any other tactic/unit I have ever used. (And I even tone down the shields a bit, basically counting all three shields as a 3HP vehicle, rather than three separate 1HP vehicles.)
Also, I think I'm the only person at my store who actually owns Stronghold. I'd like more people to play with some of the models, like VWBs and the Firestorm Battery.
