For what you are going for you might consider:
Weapon- Quicksilver Storm,
Exotics- Stomp-EE5, Cyrtarachne’s Facade, or Mothkeepers Wrap with Ex Diris.
Aspects: probably- Whirling Maelstrom & Threaded Specter- for the build/ game play you are talking about.
I would probably go with Widow’s Silk if using Mothkeepers or Cyrtarachne’s Facede. Obviously go with Grapple Grande if you use CF. For your build, go with Threading Grenade if that’s your focus.
Fragments. I use: Ascent, Finality, Transmutation, Propagation
Hope this helps. Feel free to ask more questions, always glad to attempt to help.
