I don’t think you do. however, there’s a Tier list post made by a community member. Hasn’t been updated to 1.1 yet, but should be soon.
But, as I said, Maxroll is a good place to get started.
I think they added a way to import your build to a planner, like you can in LET (although personally I think the one in LET is still better to use) but I don’t think they have submitted build guides. So it’s only the guides their team comes up with and those tend to be made at the start of the cycle and then they don’t really do many more.
