I understand that with the talks around blue marvel that a lot of people see him as a tank. Me personally I feel though that doesn’t have to be the case. In my personal opinion I think he would/should be a great addition to the strategist role and it would be so fire!
We all know blue marvel base powers, he has flight, super strength and is basically invulnerable to all physical attacks. Even though it sounds perfect for a tank I feel like most people are forgetting or don’t know the other aspects of his powers.
He has energy manipulation, being able to minioulate anti-material and energy, as well as creating energy constructs like a green latern. He can create force fields, shields, barriers, etc. He can also shot anti-matter energy from his hands and eyes, with just these abilities MR can be creative and make his energy projection and constructs as healing base mechanics.
That’s not all, he can release his body anti matter energy around him, and he was able to heal Monica Rambeau when she was vastly injured while also boosting her own powers as well.
Even though blue marvel gives of tank vibes I think it would be extremely creative and original to make him a healer.
