The fun in it

Shan watched the matches as they unfolded and was totally stunned by how, not useless, but uncoordinated they all were with different partners. 

Heck, even Chao, who played with Aijie against Hongjie and Yuyu, had been so messed up he had slashed Aijie a few times, while Xisheng had blown Chao away from the fight, right into Yuyu's ultimate attack.

"Did he just execute me?" Chao asked, totally speechless. Yitian covered his mouth, giggling, and so was Shan. Yu's ultimate was different from his own, and it was a very powerful burst of dark shadow energy that caught on a person and expanded until it burst, dealing damage, especially during the burst to anyone who was in its vicinity. 

On the other hand, Shan's ult had many shadow clones, dealing continuous damage as a point-and-click you couldn't disappear from any of them, But Shna could click two people at the same time and let the third one be, Yuyu couldn't.
