As the normal line up of Mei + Tenten + Mabui can be shut down by CC'ing or blitzing down Mabui, I wonder if there is any way to improve this weakness? Ask since I absolutely love Mei and happen to have both GNW Tenten 3* and Mei and Mabui. How about replacing Water Main with Fire Main for the anti Debuff + Shield? or Earth Main with the Shielding Mystery and Skillbroke Kurenai instead of Mabui and Water Main?
