If you have a PWC I'd say melee, although if melee isn't working out well then don't do it. Make sure you are targeting low dark blue cons rather than high dark blue cons. You can't tell just be conning a monster what its exact level is, but try to have an idea (whether it's from the wiki or from other monsters with the same name that are different cons) if the blue monster you're fighting is closer to green con or to even con. High dark blues will be much, much tougher to fight than low dark blues.
