How To Win A 4v5

Alright, so clearly Riot isn't going to deal with the issue of AFK's anytime soon. So instead of complaining let's use this space to discuss some different strategies to cope with the inevitable situation. Here are a few thoughts that come to mind. Please leave your ideas below as well.

1. Don't play support: While they have an important role to play, supports are often the weakest member on the team. Assuming you are not the person going AFK, then you increase the odds of the leaver being the support. While it is better to have all 5 members, I'd rather the support be AFK than the mid or top laner.

2. Have the Jungler take over the missing lane. So if the AFK is in one of the lanes then the Jungler should probably take over. While they may be countered and not end up getting very fed, it is better than losing several towers. And if the AFK is the support or ADC, then the Jungler needs to be camping that lane.

3. Adjust builds depending on who went AFK. If the AFK was your only tank, then it's probably a wise idea to get a defensive item. Of course this all depends on the situation at hand.

What do you think? Any other ideas on how to cope with a 4v5?
