let me apologize right of the start that i have only crossread and not read your full answer. this is what i have to say:

herby is right

we had a guy on our server attempt the same and i beat his pent early everytime that he doesnt even use her in pvp anymore, ever.
i used adam+flavi as base heroes and the rest stunners. adam hits first to wipe out the party, his pent kills someone next. then your stuners hit, flavi and herja drain.... and he is history. no more skill use ever, perma stun... no chance.
