Basically contradicting the comic lore where T'Challa was the focal point of the comic for decades and is the reason why Wakanda is what it is.
You can focus on other characters but to come here and say the comics were not about T'Challa but Wakanda and say that anyone can lead the franchise itself is not true. I wasn't until recently that they decided to expand on the Wakandan lore after Coates was hired to write the BP solo.
