I'm running petrifex, mainly because i'm new and they seem like a good way to help offset that slightly. Also my local meta seems like people run both optimized lists and Rule of Cool lists. So i'll definitely run a different legion or different builds if i start to notice people playing For Fun lists are not having a good time. Most of the models i thought were cool (And.. let's be honest, i sort of bought the whole range because i love their look) also happen to be some of our "Stronger" units. Like, I absolutely LOVE how the harvester looks and will probably run at least one or two.
