Should I use my 2 4* crystals or save them

Last time I used a 4* crystal they only had about 5 characters and I have Windblade and Mirage as 4* so should I hold onto my 2 crystals for new charecters or use them now

That's up to you.. do you find more value in having a higher chance of duping one of your 4* bots, or would you prefer a shot at a wider array of bots?

Personally, I'd want to dupe the 4* bots I have when it is much more likely to do so with a smaller pool of bots.
