Aika meant to tell which skills are more important to go for first

I don't know, but many players in my server got what they needed the most without any problems, and that was his mystery and chase .
For your information without boosting ingots as that seems to be your only argument in this matter

Well this will happen. But why did you lock 4 skills?? one of which is standard +1, i wont even suggest locking standard +2(donot look at me i got standard +2 and passive(2) +1 together in last try i will get few more frags to complete minato and switch to y+2 passive since hes my p2, just there as support). Of course it will take a lot of tries after locking 4 skills( also coupons). Only skill you should have considered locking was y chase all rest were useless

Edit: donot waste coupens daily on it, only use the free ones you get. Also donot expect it to be done before nearly 250-300 advanced trial and advanced protections. Its not some fix rate but mostly it takes that much, thats why i donot go for full skill bt usually (minato being first one of rare ones)

Can you make it sound bit clear?

What i understood is that you spent 20k on advanced vials only (not at all on advanced protections), BEFORE these results trying to get mystery +2 or chase y but you did not got either one.
