so riot finds it bad that supports are considered to be ward bots
then maybe you should make them as usefull as other champions
the only reason you would you pick suport is because they dont suffer from lack of gold ... so adc can farm and support can evolve into a ward bot ... who's owerall power is sub par to other champions but still its a safer aproach than other champ who will need to get gold from somewhere to maintain relevance
the only reason champions like annie are able to push normal supports out of botlane is because she isnt gold dependant so she doesnt suffer from giving farm to her adc ... and at the same time she is an actualy strong champion so she isnt usefull only as a warrd bot
you want to make support a role players will want ... you need to redesign botlane first ... then redesign the powerbuget's stance on stuff like utility
and then remove the sight stone which functions like open statement "this is a support and he is warding for this team"
owerall thats also the reason support isnt popular as mid or top ... since support is sacrificing his power to allow adc to get his power
