Any word on poke supports?

Just wondering if anyone knows if riot has anything in the works to help out more poke-oriented supports. Currently it just feels horrible to try and play nami, bard (without building tank), lulu, morg, zyra, sona, soraka, etc. in the bot lane because they are so far outclassed by straight tank supports (braum, leona, tahm, leona, leona). Perhaps some sort of buff to is warranted? Currently it feels a little lackluster, especially in teamfights. Currently the only squishy support I ever really see is Janna, just because she can make the lane so passive it essentially doesn't matter what supports are there.
