Iceman or colossus?

Mongoose

So I have an r4 5* iceman and an r2 5* colossus. I just got a 5* mutant awakening gem and I have 90 sig stones waiting for whoever I awaken. I really want to awaken iceman, but I’m curious what the buff for colossus will look like. So I’m putting it out here on what do you think I should do. Should i wait to see what they do with colossus or awaken iceman?

Even through the buff colossus wont be above champions like iceman, go for iceman
Edit: You might actually want to wait until you get a better 5* mutant like omega because icemans sig doesnt benefit him THAT much
