It's quite an unimportant question but i ask nevertheless. I guess it's the first time since I play that I actually do not have a shortage of 5* slice girls to lvl. But this only led to the situation where I am uncertain who I want to prioritise. The ones I'm deciding between are Camellia, Nasturtium and Geranium (also Holly, Lantana and Lena but they're kinda second priority to me).
And while I'm at it, I'm also unsure about Apple of Sodom and Mirabilis :P
(and just ignore the synergy stuff since it's just not worth the trouble for this question^^)
