Ranking up top tier 4* vs mediocre 5*
What are opinions on 5/50ing top tier 4* champs like Corvus, Domino, Havok, Omega Red, Sabertooth, Ghost versus R3ing 5* champs like Cable. I need to complete 5.3 and 5.4 so looking for more heavy damage dealing options. Just wondering if folks are stilling ranking 4* champs these days. My 5* pulls are usually disappointing.
