Looks like they gave Skaven a cannon unit that can wreck infantry (Edit: And everything else!). Those rats are getting harder and harder for us to deal with! (Edit: I can't imagine all their new toys won't get nerfed soon after release. They seem to be way to OP as they are now.)
as if the skaven didn't have enough artillery yet... In general, warhammer TW has an absolute ton of ranged weaponry. It's getting annoying.
