Well, They could allways add frieza form 5... and before you 'all go off and chop my head off with a shovel. there is such a thing for an icer to get form 5. which is the form that cooler had... (he didnt have it for very long tho... the sun made sure of that...) but that COULD balance frieza out if they so wish. and with Piccolo. Piccolo, has super Namek. (nail and piccolo combined) then he has the legendary Super Namek (Where he increases in size substantionally and so does his pl) and then there is Super Namek (Piccolo and Kami) and after when his power level grows. so does his multiplier. so that could be piccolo sorted out... and with krillian, he could have mystic then kaoken or power ups afterwards? or super human? (Master Roshi Had Super Human, Where His Muscles Bulged up quite alot. which is shown In DragonBall and the Brolly Movie.) and to even trunks out he could have. Super Saiyan. Then Acended Saiyan then Ultra Super Saiyan. and then "blah blah blah".
