They removed wolves den - but Feasting Grounds remained and Lichenweed was added. Wolves Den was largely made redundant with the newer feast maps, in fact we still refer to feast maps as Wolves Den in general because we didn't really lose much.

Slaughter on the other hand was a different scenario entirely. In terms of proper PvP in what felt like a relatively low pressure environment - that was as good as it gets. Feast is not a good entry point for people wanting to try PvP - I know it doesn't feel like it to us; but it's quite a serious game mode.
