I don't hate them together, but I do think T'Challa needs a love interest who belongs solely to his franchise.
Heroes from different editorial offices being together rarely works well, and even at the best of times there's a ton of juggling that has to be done. What if the X-writer wants to take Storm in one direction, but the BP writer wants to do something else? You can probably find a work-around solution in most cases but it adds another layer to the process that can slow both writers down and distract editors who have more important things to be doing.
Done well, I like them together. But I don't see it as a long-term possibility so I'd rather just see writers focus on the two characters individually and invest time and effort developing relationships for them that can actually last.
If the X-office wants to give up their rights to Storm and let her "live" with the Panther editorial office (or vice versa), great. Otherwise? Someone in one office or another is going to screw it up and end up wasting all the time spent on them as a couple.
