"Have you tried to buy nordgen through negotiations? "

I 'm not in that LV, yet, I'm LV3/season 3. I have 1 good nordgen but going for more 5* I was in the middle of biding war and gave up.
I have a competitive team (going for my 3rd L, semi CH.L., semi CUP) so I must have many have 5* players. In some season at the future I 'll think about tanking.
