You know, I'm still the only SM player I've ever seen use a Razorback as an actual transport... and I can count on one hand how many orks I've seen emerge from a wartrukk... I've yet to ever see anything unload from a falcon. All this talk about blob-tacs being IMBA and no one seems to feel like it might be a good idea to use transports to negate 90% of that blobs effectiveness. Why is that?
As for nids... ya, I know... this is not really a solution. Its a good thing you have WTFAOE on that Barbed strangler and sporemines n' stuff though
