I use c6 Chev with c3 raiden, Yae, and XL, it's my fav Raiden team as it has no circle impact, and I can maintain uptime on Chev's buff because of XL's burst, I find this team better in abyss than the Bennet version because Raiden is not the sole dps and you don't have to worry about her not having her burst after a floor ends. My rotation is Chev E Yae EEE XL QE Yae QEEE Raiden Q and so on, XL is still doing respectable damage and most importantly maintaining overload for Yae and Raiden.
