I'd only ever want a cross-over event that didn't only release male specific outfits or 1 specific outfit as well as hairstyles. We have enough short spikey hairstyles that just look terrible & need more long-inspired hairstyles.
I didn't even participate in the FFXV event due to the lack of good cosmetics- that & FFXV just wasn't any good & not worth the attention it had gotten.
