Well technically she's not currently immune to janna's w, ryze still has his w, annie still has her q, fiddle q, rammus e, warwick ult, malz ult, skarner ult, urgot ult, lulu w, maokai w, lissandra ult, leona q, tf w, renekton w, voli q, udyr w, vi ult, naut ult and passive, nocturne fear, blitz w, karma w, poppy e, etc. Yeah she wasn't fun to play against, but her passive doesn't mean she suddenly becomes immune to skill shots. Any wide skill shot is still easy to hit on her since her jump isn't anywhere near as fast as a flash. Any cc skillshot that you can aim properly is still going to hurt her, and now that slows make her auto attack slower, her mobility and her damage output is lowered by one form of cc, which doesn't happen for any other champion.
