Support?
Don't you mean bot-lane apc with some AD support that farms?
That might explain why you're still bronze
This is the kind of thing that makes me think that League's gameplay naturally encourages toxic behavior.
That said, I love stealing jungle buffs and kills as support.
Adc "Wth, that's like the fourth kill you've taken, you're a support, I need the kills"
Support "Im supporting myself now"
I always try to let the ADC get the kill except in 3 cases. 1: They cant get it in time, or not there. 2: It's a team fight in late game. 3: When the support is being extremely extremely rude.
