Ranger Preparations....
Well first I would like to note that we do have one: Sharpening Stone. But, unfortunately, it seems that the preparations you speak of are already implemented on the Thief in the form of Venoms.
I think it’d be kinda boring if they were implemented as they were in GW1, I thought they had a long cast time and hated reapplying them mid fight but it’d be cool to see them return at some point.
i find that they could replace spirits, more viable and they can’t die
