Missing 5 star champions

Why have the likes of wolverine, vision, thor etc never been added to the 5 stsr crystal?
Do you think they ever will?

Because as 5* kabamm thinks they'd be to over powered and they prolly won't be added unless they do it after 6* are released

Kabam thinks they are more powerfull and usefull than blade, starlord, hyperion, magik, spiderstark, iceman, archangel, Angela, etc.

I think SW could be more powerful at a 5* then your list
