What does a good Spinning Attack, Asuran Fists and Ascetic's Fury gear sets look like?
Spinning Attack is kinda based on what you want to do. For max damage you want multihits and set will be very similar to Raging Fists or Howling Fist. If you want to use it to clear group of trash mobs tho, then going for WSD might be better option. the reason for this is with multihit you will make more damage, but it wont be evenly split. Multiattack will proc for each target separately, so some mobs can get hit by 8hit Spinning dive doing 16k, while other by 2hit Spinning doing 4k. That will further result in some mobs dying faster than others and at the end you might end up killing whole group longer with multihit set, than with WSD set.
Asuran set is pretty much as much STR/att/acc as you can get. Relic +3 5/5 is great candidate. If you are super buffed through the roof, then you can use 5/5 Malignance to take advantage of PDL that this set provides. One thing that stands out in comparision to other h2h WS sets is Fotia belt over Moonbow belt (at least if you care only for damage and not for capped subtle blow or -DT).
Ascetic's Fury is pretty much the same set as for Victory Smite.
