Breeding S and S without blessing

I don't think it's a bug. I think the A+ is just to annoy people.

I think that breeding pure S monsters should result in a monster that is either equally as strong or stronger, or in this case, just equally as strong, like the other grades.

Really, I think it's just for perfectionists.
P.S. Being a perfectionist is not always a good thing.

Yea I just bred my neo again because it had A+ in mattack. I didn't really need it if I'm using thunderstorm but I just couldn't stand the fact that its not pure S hahaha

I have bred many dracos for adaptability(15) and still haven't gotten it, but it has given a good view of breeding pure S. I haven't used blessing besides to get the two pure. Most have been a single a+, rotating through the skills. Maybe three of them had two A+, one was also a pure S.
