Six star rank up help

Mentalboy1

Hi I need advise.
Thinking of ranking a six star to R2 and narrowed to thing or diablo.
I do have both at 5*
Thing 5* is duped and r5
Diablo 5* is R3

Now my thoughts are
thing is good defence but not massively good offence. I do have 5* human torch and 5* Mr fantastic (not ranked up yet)
Diablo great regen just need to learn his play better. Now I could awaken the 5* which may better? Or could be crazy and do both diablos??

As a note I don't run suicides which I now helps him.

I dont know why you have Thing ranked up before Torch as a 5*

Diablo and Thing are both great. Thing is a better two way champ (offense and defense) than Diablo is.

If the opponent is poison immune it basically negates diablo also.

I would lean toward Thing. Defense, offense, and some immunities. Or just hold until you get a better option.
