I have been a pretty big tourny person although I play in a lot of indy GT's so iam used to see non gw stuff , but as lng as it is in the spirit of the army i say go for it , I have had the pleasure to see some fantastic non gw 40k and fantasy army's . dont blame someone if they like the game that all there peers play but don't have the money for some gw stuff . There prices are through the roof way more than they should charge , I have been playing this game a long time GW keeps on getting more for the money rather than the hobby year by year , you think it was game play that made them make troops the only unit that can claim an objective , it made almost everyone that played elite armys have to go and redo there list and buy more troops .
The above pictured stuff really ant that bad at least they changed the weapons to make it WYSIWYG .
And also indy events is where its at , little to no young rude kids , fairly priced , and offer a prize in models if you win and the trophy , they also take the time to have a hotel close by give special rates .
