Low elo ADC and keep dying? Support is low and flees early? Guess what?
It's your own fault, not the support's. We support mains know how vulnerable you are early game, and how we play a critical part in helping you get that late game power that will win the game. We get that. We also know that the more kills the enemy ADC gets, the faster they become powerful.
Do us all a favor, and flee sooner. If you can't and we can, don't bloody whine at us just because we did. We may have spells on cooldown, or maybe we don't have the mana to do anything. Hell, we might be too low and not want to risk a double. Stop blaming us for your own mistakes and take it as a learning experience to play better.
Oh, while we're on the subject, allied players are never MIA. I don't care what we do, stop pinging us as such. That goes for any role, actually.
