User blog:Arkxiah/These summons recently

So, I just wanted to ask if any body else, on the past 3 omni batches have gotten only five star units generally with no omni capability?

I've wasted way to many summon tickes on five stars to be honest, and I'm back at a single gem with nothing to show for it.

Should I just buy gems or is there some sorta "best time" to summon?
