Yeah. The second zone was a big pain for me to get through. Loved the first one, but despite there being some stellar little mini-stories and characters in the second zone it just kinda felt bleh.
But getting through it is totally worth it, Transylvania is fantastic.
Slog through it at some point, IMO. You can always replay the older missions on the same character if you want, as well, so at least you won't lose all the progress you've made so far.
