I don't know about you but that's actually quite a big difference (and would say that Fersen would actually fear more the Isolation than IMM). Actually they can (aftermentioned ninjas ;P). Or repeater can :P I'm not saying Fersen is usells. He has just (probably) even bigger "Asura problem". Tbh I wished he had some "defence" program just to make him a tad bit better on defence against KHDs skirmishers (Breakwater ?).
