LuLu is still a toxic champ
No one can touch who she is protecting, NEVER [zombie-brand-facepalm] Huge slow, ASMS buff, Heal/shield, Damage, knock up etc.. Become more toxic in this CRIT ADCs meta*[sg-ahri-1]*

is mechanically intensive and has a high skill ceiling.
I've been playing a decent amount of her and I feel like the issue is her polymorph atm. Imo, lulu should be an enchanter that is supposed to support whoever she chooses for a more aggressive style. If I see we have a bruiser with a good gap close ability that can carry teamfights like jax and yasuo, I will usually ult him for the knock up/slow and also speed him up. However, some games I will just feel relegated to pressing polymorph on the enemy assassin and then they become useless. This is especially true if the assassin is someone who can't dodge her polymorph (Lulu's polymorph has a cast time, so zhonya/fizz e and other abilities can dodge it) then they will feel useless vs her unless she messes up which can honestly be quite frequently. Shield/heal type of items on supports I think is also causing the pealing issue to be a little too high.
I play her quite a bit, and can honesty say she is meh as a support. I main her, but there are easy ways to kill her. She is squishy, and has very low base movement speed so catching her out isn't hard. She can be a pain with something like a stun, or other cc. She certainly isn't the best support right now, but she could be if they touch her. 
I love lulu [sg-lulu]
