Well my warboss is dreaming of starting a WAAAAHG! that large. I was thinking because he was part of a huge WAAAAGH! that battled the Gigantic tyranid fleet before the Imperium shot the Emperor. He became the warboss of one of the feral planets and is looking to relive the epic battle he fought against the space locust. I don't think my character would actually be able to make a WAAAGH! a big as Ghazghkull's but he is ambitious enough to try and make one.
