Hello everyone!
I have just pulled a 5* colossus and am super excited! I have never really used him and I have a few questions for those of you who are more familiar with him.
1) What is the most effective way of using him? This isn't me being lazy and just asking for help, I have watched multiple youtube videos on him and I have seen some people suggesting to spam sp1 others say focus on sp2 and some say a mix. I would love opinions of people who use him on what the best method of using him is? I know parry-heavy is effective, but I'm not sure what else. Please go in detail if possible, I love having a blue-print for my fights it helps me stay focused and play better!
2) I am close to being able to r4 my first 5* and he seems like the obvious option. I know he benefits a ton from his awakened ability and synergies, but he still seems like a beast without it. Looking at my roster, is he my best r4 option over sym supreme (he's new to me so I'm learning him as well and not very good with him) and red hulk? I don't have any other even relatively usable mutant option.
Any overall tips would help a ton! Thank you all very much! Hopefully Colossus will help take me to the next level
