Best Mjolner Class and Skill Tree 2.2

The Path of exile Ascendancy has opened up many different options for my mjolner build. I could go scion and go To Mara and Duelist while taking the witch or shadow alternative start. alternatively, I could go Mara or Duelist Alternative Start and head North to Witch or Scion. Alternatively I could go some other class such as Witch, Shadow, Templar, Marauder, or even Duelist due to the OP absolutely broken spell block changes. What do you guys think? Also, if Possible, could I get a tree?
