Gear looks pretty damn fine to me.
It's perfectly fine to have 20% Phys instead of CC on neck.
As previously noted.
If weapon is gifted, roll AS to 10% Dmg. Or roll socket to 10% Dmg.
If you didn't reroll Chest to 3 sockets, reroll goldfind to Elite Damage Reduction.
Get a new pair of boots, you should never have MS on the actual boots. Get the full 25% from Paragons and get Skill dmg on boots.
