You know what would really help make support feel better to play?
Making them not so reliant on having a good ADC. When your ADC is bad you feel completely useless and you're starved of gold and EXP which is already hard to get in that role. Roaming isn't always an option either because the other lanes might not be able to follow up very well or might be losing too hard. It's kinda shitty that your performance is dictated so heavily on 1 player.
I guess this also goes the other way too. Getting a terrible support while playing ADC has got to feel like crap.
