Ignore Resist makes Weaken useless.
as mentioned above, you could use +2 to +4 all Sets. this will make your Set (Green) affixes more powerful (8 is max).
Timewarp Proc isn’t really needed, as it is only increasing the damage of the Throw Sword Proc, and I think Boomerang & maybe Whirling Blades.
also, +1 to +10 All Skills. this will boost the damage and special abilities of all Procs and Skills being used on your Build by +1 for each +1 all Skills.
put an Epic (Orange) +100% Weapon Damage on your Chakram. this will increase the damage of your MH Skill and all Proc Skills that do damage.
putting some Stat Points into Power will also increase your damage, especially if you put in the +100% WD.
you might not be able to make all of these changes, but the help written like this will help the most.
