Tech rank up question.

Alpha07

I have 7 tech catalysts and i can either:

R3, and R4 5* Ultron (Unduped).
R3 5* Ultron and then R5 my 4* Sparky (Duped).

what should i do? Thanks in advance.

I would suggest to go with the second option.

Unless you need a immunity champion to run AQ map 5 or 6 lanes

Otherwise, if you're good with sparky, it will make your life easier in EQs every months and AW

Depends on who you are most comfortable fighting with, personally i would take the R4 5* in my roster over the 4*
