Return of Reckoning

As the subject says.

On my IB, the Dominator set #5 bonus (10% chance to Taunt on hit) only triggers when I use 2h weapon. With 1h weapon + shield, it never triggers.

bugs go to bugtracker.
how many times did you swing?
at least 100 for evidence.
better to same target but condition is hard for testing, 1day long test in SC/orvr would be enough evidence.
