People who equate some mild nudity with "sexualization" have some serious personal issues that should be worked out.

Also, it seems to have stopped people from discussing the actual interesting parts of what's presented in that fight - for her ultimate she seems to strike the exact same pose as Hydaelyn in the mural of the Sundering, and her transformation in savage seems to look very similar to Ran'jit from the solo story fight with him. Could be a hint of something to come, but at the very least they're cool callbacks for people to notice.
