[quote=@Crimson Flame]I don’t know how I feel about sacrificing the other two Digimon. It feels unnecessarily sad. I know they’re not technically dead, but we thought up personalities for them. [@Lord Orgasmo] gave his mons nicknames and everything. We get attached to them, and now they have to become cannon fodder for our main Digimon to be able to evole?

I get what you're saying. I don't want to anyone to sacrifice any of their Digimon if they don't feel comfortable with the idea. How about we just let each person decide for himself how he/she wants their partner(s) to Digivolve? For me personally, it makes sense that only one of my partners reaches Mega stage eventually (tho all 3 of them will have personalities), but I guess there's nothing wrong with people maxing out all three of their creatures.
