Mariner was a complete joke until he got a rebuff MONTHS after initial release. He's still a joke and only used to counter LAD's fury.. otherwise NO ONE would be using him. Be honest.. if it were not for the counter-LAD aspect of Mariner.. would you EVER be using him in PvP? Of course not.. there are least a dozen other characters better suited for PvP support.
Pilgrim could be a complete dud... like The Mariner.... Like Ragnar.... Like the Mercenary... there's really NO WAY to know.
