Roleplaying PvE Ranger - Help switch it to Soulbeast

With the release of PoF Soulbeast became avaible for me and I wonder if it might help my little Asura Ranger.A lot of way better players than me will be shocked in the following, but I use Axe/Warhorn as my main weapons with a GS in the alternate slot. This is simply for the flavor of doing it so, because I use Frostfang & Howler on my "Little Queen of the North".

This is my current build

With it I got through a lot of content, but I know that it is far from the best possible Ranger-build. I use it mostly to keep up as many boons as possible and power through with them.So now I want to switch in the Soulbeast specialization, but am unsure if it is better to replace Marksmanship with it or keep it as it is, as well as what utility skills might be better to be replaced.
