Lightbringer

How about bringing an item similar to Lightbringer to Summoners Rift? I really like that ADCs have new options to go to for attack speed but I would really like to see new options for Critical Strike too. Right now, all we have is Infinity Edge which is almost guaranteed to show up in every ADC build and then Essence Reaver and Trinity force which are only build in a few builds. I'd really like to see a different option for ADCs rather than Infinity Edge.
