Well... Pure coincidence LOL All my echo talis are Fierce (ATK/DEF) and so Advantage (Overwhelming - as well ATK/DEF)... I had those maxed out at hand so I put them... First thing was to build his ATK, then DEF happen like it is...
P.S. To be on topic - yes he's NOT the best Eddie Gunner I used - and it happened I've tested and own all of them beside AHE... Mainly because his fury is pointed not at the crowd but at single target...
