Tank Swaps how to do it right?

That's easy.
1. Just keep attacking (debuffing) the boss until you approach the split.
2. Acitvate Defiance and start building hate combo up to Skull Sunder or Butcher's Block until Caduceus splits.
3. Press whatever button you use to switch through hostile targets. This will target the split.
4. Provoke, combo attack, start running, Tomahawk till you are in position, keep using hate combo or Storm's combo as needed.

…… you have to Provoke the second snake? Usually I just switch targets and 2 tomahawks is enough to get its attention for me.
