Black Panther's habit has been virtually the same, given modifications and some variation since he was created in 1966! How could this Wildcat mess have any legs?
With regard to Shuri, I was one that did not originally like the idea of T'Challa not being Wakanda's lone Black Panther given the cultural and political significance of the office. However, what Hudlin did with Shuri was introduce a level of diversity into the Marvel U and BP mythos in a brilliant and brave, but common sense manner. It makes sense that T'Challa would not be the sole heir to T'Chaka's throne. For the good of Wakanda, it's future (ironically) should never be subject to the chances surrounding a single heir who would repeatedly be involved in life-threatening endeavors. Hudlin resolved this with Shuri and gave her the weight and gravitas of a viable monarch; one who should be respected and could meet the eye test as a true hero in her own right and not be relegated to some macho comic-dom damsel in distress category. Credit Priest with the Dora Milaje and QDJ and isn't it interesting that you have two creators who happen to be African-American furthering the cause of inclusion and diversity for women and people of color in comics. How is it that there is no place for them in the medium? Hickman has wiped their creations and their legacy from Marvel Comics.
My two cents!
Peace,
