Drag is too strong right now.
While I understand that drag is meant to be a priority objective in most of these games, it is just far too rewarding. With the ignite per hit plus the ap and ad bonuses, not even considering the other bonuses, its basically a free card for teamfighting for the next 5 minutes which, most of the time, is just an auto win. On top of that, the team that normally gets drag was winning anyways, so it basically makes comebacks in Season 5 hopeless especially when combined with baron.
