Thanks for your reply.
He is wearing max runes and max sword/spirit, also all talents are maxed.
I am pretty sure it has to do with running out of rounds, though my comparison to the other guy left me quite shocked.
My best stunner is Aphro, Cianna and Shayd are nice seconds where I find that sometimes Shayd will stun more, though her damage is dismal compared to Cianna.
I will run a few days with Pompey in sub instead of Thucy and see if what the outcome will be.
