If both of those are picked then pick your best laner. If everyone else already picked a defender and all attackers you might be better off picking a support but ONLY if you are at a rating where the average player is as good as you are on average.
This is basically what I do when I want to climb. Usually though I'll just play whatever I feel like. And for which items it's hard to say for attackers since 2 new items were added and no one knows what's best so far.
