Lulu is poorly designed and is toxic to play against
She has high poke and shield in lane, she's Xerath 2.0 in lane except with even more kite.
Her counterplay should be jumping on her face and stomping her ass in a duel.
All you get instead is silence/slow and she gets shield and knock up and 500 hp.
This is poor design.
She's overloaded and the only way Rito found to balance her was to nerf all the numbers in her kit at the same time.
Stop overloading champs and maybe make her kit have clear strengths and weakness.
