Will there ever be any meaningful Senna nerfs?

It feels kind of like there's no counterplay when support Senna can walk up and Auto Q Auto you for 40% of your HP and heal any damage you returned, so you either run away and take the same damage or maybe escape the Q, and keep getting poked down, or return dmg and she's healed half of it or more

then there's ADC senna who does the same but more damage, her trades are way too safe, can we reduce her damage(as opposed to reducing healing during trades) so she doesn't become useless as a support, or reduce her range(like you did to Lucian for literally the same reason)
