A question, I have 20000 feathers again and I pulled a Erika 4*, the problem is she is -SPD + DEF, would you upgrade her? I was thinking convert her in my main buffer given her dance and cos it has + def would be a bit more bulky to defend while she gives buffs to my Nino, it is bad idea or should i wait till I pull one erika with +SPD? Maybe is better upgrade an olivia? I also have a kagero 4* -DEF+RES and I like a lot Kagero but I was waiting to pull one with +ATK
Wich unit you would upgrade? Keep in mind I am F2P and I don't think I will pull a lot of more reds or greys as I alredy have good units like Lucina, Ryoma, Marth, Lyn, Sanaki, Klein and 2 takumis.
I really need blue and green units, maybe I wait for a 4* Robin?
