More like not even started.
If Challenge Descended 3 has Zhao Yun on it, I'll surely focus on skilling him up there.
Of course, I can always drop someone else to put a shield in, but that someone can only be Skuld, who is bulky enough as she is. If GZL is on the team, surely I cannot ditch the attackers, which Liu Bei and Mikey are.
Then there's the option of Susano who I think has an attacker ult? - - but it's way flimsier than his balanced ult. He's also not ready for use, either.
