Can confirm, as a die-hard vermintide fan - this update is crap. Costs twice as much as any previous DLC, only one new map (I was already kind of miffed that the Bogenhafen DLC only had TWO maps), raises the level cap to 35 but instead of adding another set of talents, it just takes away the level 30 talents and puts them back at 35, so it just increases the grind.
Throw in that it's buggy AF and has a whole lot of "rebalancing" that everybody hates, and all in all, this might be what kills the game, and maybe even the series.
