I really wish Falcons were more viable these days, but their halcyon days of 4th edition are a distant memory. Even with these drawbacks I would imagine a lot of Eldar players are like me and have at least one of these guys hanging around. In the days of Wave Serpent spam and the much better mono-purpose Fire Prism, the Falcon is the least viable tank in the book.
Even with all that, I still felt the need to paint one up. With the majority of my play army finished, grinding out the lesser used models are slowly becoming a higher priority. It's painted in my standard tank scheme with the colors and stripe placement. I didn't really feel the need nor desire to go above and beyond on this guy.
I have two Forgeworld projects on the table these days. The Warp Hunter is very close to the finish line, whereas the Lynx is just in the preliminary base coat stage.
