If sunday Dosen't end up being Castorice's BIS teammate how will you feel about it?

At first some people were saying Sunday and RMC will be Castorice's BIS teammates, some people argued that Sparkle would be better but since Sunday was made specifically for Summon/Remembrance characters it made sense he would end up being her BIS in a hyper carry team. But now some people are saying Castorice would probably want Tribbie and Mydei in her team with a sustain which is far different than the original hyper carry setup.

So back to the main question if Castorice truly ends up not wanting Sunday in her team how will you about it? I personally would be really disappointed as the reason I pulled sunday was to get a strong harmony for future Remembrance characters.
