Rank up advice, 6r2 or 5r5
Hello everyone, I need rank up advice. I Just got domino as a 6 stars and I don't know what to do. Should I rank 2 domino ( I have 4 T5B)? I only have one rank 5 so I don't know if this is the right choice to r2 a 6 stars. This is my roster, any advice is welcome. I'm cavalier, I complete variant 2 and 3 (working on the 100% at the moment) also I didn't do any path of the LOL.
