For my fire wizard I crafted the robe, and went through Waterworks to get the full set. Honestly, if your gear situation is bad right now then most definitely go for the Wintertusk gear so it'll take you through those Waterworks runs.
I always craft the Wintertusk and then use that pretty nice gear to help me get through Waterworks and House of Scales. Some wizards actually prefer Wintertusk because of the extra blade and trap that it offers.
gear in Grizzleheim or just get to level 60 and farm for Waterworks?
