I like the look of his tier list but it does shatter one of my hopes . . . that there might have been a Rhulic character warjack in Colossals. I was quietly wishing for a character Driller that had a "magno-grapple claw" that could pull models in to be drilled apart . . .
That said, the Tier 3 benefit has me hopeful that his list of upkeep spells will be solid.
