Your not alone, I'm also not been able to get the CU. Not as high on level as you (Lvl 95) but also trying for till day 1. I also give up, sometimes between the much event whe have trying to get it. I just give a suggestion for s8 a while ago to put it on a battleground or tournament, or another possibility to get it for us who can't breed it. Still doesn't heard from them. Hope i/we get it some day.
