I'll officially never ever EVER summon on 'em again.
The chances of getting what you want are just so slim, worse than on normal banners even.
I just spent around 250 orbs for 1 Sanaki and 1 L!Ike. Both of which have +HP -Spd.....
Man... should have really gone for the Myrrh banner....
I have been pulling for Myrrh since her release, and I finally got her tonight. After a mounted Eirika, Hawkeye, Fae and Rajhat, I finally pulled her, and she is +Atk -Def. At least she isn't + Spd, but really any banners can go south quickly. It just depends on the consistency of your luck through the layers of RNG.
Those IVs are not bad at all. And at you got something, I'm sitting here at 11.50%. These legendary banners are horrible for getting what's on the banner, good for fodder if you get something good. "If" being the key word here. It needs to start at 10% and/or allow for a free first summoning session. Otherwise, people shouldn't even summon on these banners. And the release of L.Ike means no free Gunnthra, sadly.
I still want to break that pity rate, but I won't much more happy if I do. I'm probably going to blue balls on all banners except limited time ones. I already have a bunch of great units, and powercreep in nothing in my experience. I'll still be able to defeat any unit no matter what.
