During the game, I actually did try for about 7 minutes when I poked the enemy Alistar (was facing Ali/Blitz bot) down to 1/5 health and she wouldn't attack even though Blitz had already left the lane (I had it all warded...). After that, I said screw it... ended up going 0/7/1. Don't care. One bad game because they didn't want to work with their team mate.
What's the lesson? Work with your team mates... When they say 'I cant do (role)', listen to them and work with them, don't force them to do the role.
