Strange rank up dilemma

Blasthammer4

I have an awakened 4* r4 40/40 Carnage and a 5* r2 35/35 Iceman. At the moment, I have the resources to max my Carnage and I am in the process of collecting catalyst fragments to r3 my Iceman(I have 2 t4 Mutant cats and am short of nearly 19k catalyst fragments before I get a 3rd catalyst)(the process of t4 Mutant catalyst fragment collection for me is painfully slow, even after I have been playing the game for more than a year) , I'm a lvl. 44 player with a prestige of 3.4k. So, should I

wait till I form the 3rd catalyst,and then r3 Iceman

I voted for iceman since a five star gets a bonus against lower star rated fighters and has a higher upside potential to grow to higher levels. He’s also does automatic cold snap damage and has ice armor for big hits. Carnage, even after his recent changes, just doesn’t offer as much on offense or defense.

Iceman has triple immunity, ability to ignore evade, and it’s a 5* game now
