Not a fan of 2 of those crossbows. The Offhands, Focuses, Totems, and Wands all look good in my opinion.
Will there be a unique x-bow in S6? If yes, why not? 
It looks like they are getting ready for the Spirit Born (jungle monk).
Still missing an unique offhand and unique totem
Wheres my Black Shard of Belial (made up unique)
Unique Focus
8% Critical Power (This is critical strike and critical damage on one affix)
20-30% Lucky Hit (higher than normal lucky hit)
30-40% Ultimate Effect and Cooldown
Lucky Hit 5% - Restore 10-14% primary resource and reduce the CD of your Ultimate 1s.
When you cast your ultimate also cast blackhole at a random enemy.
Blackhole lasts 3 seconds and deals arcane damage (works for tal ring) and knocksback enemies to its center every 1s.
Impressive. People with imaginations these days are lacking.
That onyx dagger if not zoomed in and/or looking at a high resolution closeup of it has the unfortunate happenstance of looking like a certain type of innuendo item… Devs might want to add some sharpness to the textures so it looks like a dagger and not like something that goes where the sun don’t shine.
And they still haven’t figured out how to make a mace that isn’t ugly as sin.
