Hotrod is my favorite camo pattern. Not for the flames, but because it is the only camo pattern that replaces the rust and grime normal and specular maps with something that's... well, not rust and grime.
I like that. I want more skins that do that. I prefer the look of a showroom model over the look of the century old war machine beloved by a veteran mechwarrior... wait that came out wrong. The point is, I would like more shiny rust-free camo patterns, ones that aren't in a $500 package.
