Here is my sPvP build I have been running, I use a variant in WvW as well with good results.

This build requires knowing advantageous positioning and how to properly kite each class, so far the hardest class to face with it is Ele, Engie can be a headache as well.
Will update this post more in depth, the quick and dirty is engage with Basi Venom and While in Unload pop Assassins Signet if any projectile hate stop Unload and AA till there’s an opening them use unload.
