Sorry man. It's what Ob posted two weeks ago. Though if you have anything with other characters, feel free to toss that up.

Well, like Savers digivolution is based on willpower, right? So could trade off easy digivolution for weaker forms. Or 02, with digieggs - more armor forms which are not limited by anti-digivolution fields and can be more flexible but armor is weaker. Then there's just considering the god-tier digimon and certain flavor text (we all know what I mean).
