She seems pretty similar style of hero on paper. Basic attack passive rewards sticking on someone. Q is the same but with some extra ability. W allows her to survive the dive more. E swaps out the point and click ability which was strong into something that's slightly weaker but has a bigger potential. Her ulti is pretty different but offers more teamfight power.
It's prob the rework outside of WW that seems to be the most true to her old kit. If this translates to something completely different in practice then I'll be a bit disappointed. Used to love irelia.
