At least before I could own on TT, Dominion, and Aram. Epic shields and epic baits. She could make amazing saves with a well timed shield/heal combo and was fun to play. Sure, she had a difficult place in SR because of the meta and deserved some tweaks, but holy crap did they screw her up..
Now she plays like some boring pew-pew poke mage. Her Q has the same ratio as before but is a crappy skill shot. Her mantra Q is decent IF it hits and IF the enemy champ sits there (which they don't). Her W seems schizophrenic, as it encourages her to be close while her Q encourages her to be far. Her E, dear god her E.. It's like paper bag quality to her old shield. She's now boring, quirky to play, and she sucks on every map. Oh yeah, they even managed to remake her cool strut animation into some weird slow mo run. How did Riot manage to screw this up so badly??
