for all those in the Xbox region - from the 17th there is a release with sunny spells
moving over to PS4 - about the 18th we will also see a release with a touch of cloud
PC will have had the DLC for 2 weeks, and with low pressure from the forums moving in from the south there is a 50% chance the DLC will be nerfed to death before it reaches console.
I like where you refer to PC as "test environment".
However, there are no grinding spots as far as I can tell. There is mainly wildlife in Wrothgar (much like single player TES games), and they don't spawn in huge packs that are worth grinding. Your best bets for farming are the two public dungeons (with the rather awful exp rate public dungeons usually provide) and the Maelstrom Arena in normal mode.
