Is Mars actually secretly ridiculously op

[Ginzo Force]

Bulwark 70% reduction + armor 60% reduction + crimson guard 60% chance for flat 70 dam reduction

I assume all m2s are considered physical attacks, pair this with eternal shroud, heart of terasque, radiance, this is basically unkillable right?

[Danaie]

If attacked from behind he's meh, Hex, Urn..etc. There's no hero that is "op" if by that you means he has to get nerfed
