I had the same thought a while ago.
Built a DW tactician, themed after Gaara from Naruto. Its one kf my stronger guys but im a noob and all my guys are pretty janky. The issue i did run into was pierce/phys.
Gaara uses 2 mythical havocs, does decent damage but could definitely be better. I dont think i ever uploaded the level 100 GT link, but heres a link to my OP about the same kind of build
