Sunday's value for lingsha/jade team

I had a discussion about the value of Sunday in a Lingsha/Jade team all the people I've asked said its not worth it to use lingsha in that team and just wait for other characters is it really bad to use sunday to buff lingsha I think its good every action will give jade 10 stacks for her fua and our Lord will give lingsha every stat she lack as a sec dps so what do you guys think?
