"Range expending weapons/shields : clio (doubles zalure range and gives a nice 100+ TPmax boost), stick of chao ( doubles shifta and deband range), all kind of merges who will boost range and effectiveness of your techs."
striker of chao
and no, not too great
use PARASOL, YAAAAAA http://www.pso-world.com/items.php?op=viewarticle&artid=2363
that is if your fo can equip it... if not i know alot of people use that box thing, still better than striker
i also dont like your categorizing 3 types, theres no reason any fo cant throw on parasol for buffs and heals
switch to glide for debuffs and toss some rafoies on those dorphons
at least thats how i play
i also know people to use justice mechguns etc but i personally dont
and a solferino? never something recommended to me but whatever, its your guide
