Three questions.
1. What are all those pistons for? It doesn't look like there's anything on the edge two.
2. What are those Sir Killalot claws doing, besides making the bot look cool? They only do damage on the concave side.
3. What's with the big SURGE thing in the picture?
It's a good design but it needs more weaponry, or else needs to be shaved down to a MW. One Dreadnought weapon isn't going to cut it on a HW.
