Now, I know Uber have said there won't be new factions and that's actually fine. Sure, would be fun and all, but things is as things are. Would mess with balance and all that. But could we at least get skins for units? Something to make them match the style of our commanders? Or maybe some customization when it come to looks and not just color and commander?
Making all those models is really expensive and the main reason why there wont be a 2nd faction most likely. I think.
Learning to model is easy enough. Do a quick google search for 'blender' It's a free tool, and there are lots of 'how to's' on how to use it around. I recommend just having a play with something simple and take it from there.
