Very very unlikely.
Ei electro archon count as support character designed as energy battery.
1) C1 gives bonus resolve stacks from
so i suppose it meant that she would work with OTHER electro characters.
2) her Q designed to benefit from high energy teammates to reach desirable 60 stacks Beidou has 80 energy cost.
3) what a electro character require battery to function properly = ms. Pirate
4) ruining interaction between Electro support battery and other Electro sub-dps that needs a battery to make solo damage of said support bigger, is definition of insanity.
5) if not Electro archon then who the hell can make use of Electro Resonance.
Beidou Q worked in beta during Ei Q, but then they were like .....
"Lets spice it up".
I can bet many of players that heard about Electro archon that is battery and can make of use Electo Resonance thought about BEIDOU , since what else electro character needs battery? 0.3% Lisa mains? Most of us were like
"Electro character with 80 energy cost that needs battery, my god its PIRATE QUEEN"
And there we go with Sara C6 that boosts only electro characters..... so people were in hope on MONO-Electro squad, to make big use of Sara c6, but seems we gonna use Sara with XL XQ and Bennet.
if these is her best team .... since seems bannet+Sara can snapshot XL Q......people gonna lose some brain cells by laughing while rolling on the floor.
