I have pretty much given up on playing support to random people.

Thing is, I like taking that role, but whenever I lane with someone other than a couple of my friends, I end up with an AD carry that is either a timid bunny, or a suicidal lemming. He either expects me to do all the work (I once laned with Akali who just sat in a bush, didn't farm, and waited till I Q someone with Blitz), or towerdives at half health and then chews me out when I don't follow. Best case scenario is that we lose control of the lane and end up towerhugging for the better part of the laning phase.

And I'm usually the one to be blamed either way.
