Oh my god, my friend and I have been saying that since Thresh game out and Leona is equally terrible after level six. They have so many options to set up kills/tankiness and it comes with little to no weakness. One could say they have to put themselves in the middle of the fray, but lawd jeebus, maybe that's why they're designed to be tanky with stuns/slows.
... I'm a little bitter toward both champs. 
no, thats just it. LEONA has to put herself into the middle of the opponents to be effective. otherwise she has only her ult to work with.
thresh doesnt. he can play passive if he wants to. if hes ahead, he can play aggressive and dive into the frontlines, if he and his carry are behind, he can play passive and is still very effective at saving his teammate due to his lantern.
for leona to peel or engage, she always has to jump into the frontlines, which makes it close to impossible for her to play passive. if shes behind, she often doesnt have a choice but to trade her life for that of her carry. while thresh doesnt have to put himself at risk to save someone.
