Return of Reckoning

What the point in Invader's 6th bonus for WH/WE ?! Proc 10% on crit, which triggers extreamly rarely. Full set just losed their value to wear..
Ok make it 9 sec not 5, or 15-20% and not 10%. I just spent tons of hours to farm it and got nothing..

10% on fast hitting, crit based dual weilding class ? seems fine
there will be better sets later, no point making invader overpowered( unless you are WL, +10% crit to CS, why not)

6th bonus is a joke...even if it works well, 5 seconds is nothing. Overall the set is fine.
