I got normals win 1000 last night playing Leona support, i went 8/1/15 got a double kill a couple of times.
getting fed as a support is fun because so many times you can get your adc fed and walk away so they can last hit for the kill and dont even get as much as a gj or thanks from them.
I can say it has gotten slightly better since i first started playing but unless you are playing with people you know the chances that you get some credit for doing a great job are limited.
Getting fed as support once your adc is fed makes it so tough on the other team becasue the adc is doing all the damage and the support depending if they are bringing utility or extra damage become so scary that the other lanes have so much of an easier time.
