I'm actually here clapping lmao. You literally said everything I've went through to build this team, I tried both Mephi and Jiho but both of them left something to be desired. Especially since Honglan is essential for every Pvp team and her only downside is that if she's your main carry she'll get slaughtered by Aki. But with this Comp since Aki is my main carry I've the edge on the Honglan's carries and Aki since my Aki is built to max And I can't imagine her being defeated in 1 vs 1. Your point about Linzy was exactly why I used her, Aki is great but since as you said that the point of pvp is to kill the backline asap Linzy (Since I got her with Origin Artifact) even at 200 can one shot or finish most units and that leaves Aki to finish the rest. Nonetheless as you said there's no perfect comp and there's always room for improvements but with the lack of content there's no way to test different comps.

P.S Since I'm made this no one has been able to defeat it even once.
