Still feel the same Decom? ^^
UD are not that more difficult to deal with than orcsies. Combine deep chains with ambush and you'll have them at desirable nw size (=crappy gains) in no time. UD tend to do anything to keep their leets (releasing def, ospecs, thieves and even wizzies). Capitalize on that notion and even if they crawl back up, they're shut down just as fast without having to pull away much resources from other projects.
