"One of the bigger problems in the game is that rapid fire exists" - Scarra

"Rapid fire and the combination with shiv gives ADs poke... It's a poke spell on a cooldown, a free harrass, free siege, free poke spell on a cooldown; it gives them safety in teamfights. Range is a really, really, really important stat it's probably one of the most important stats in the game. And I dont think people talk about it enough the fact that range actaully its one of the biggest problems in the game where yo have to deal with champions that have 700 range harass..."

I couldn't agree more. I think it's disgusting that Crit ADCs can poke a third of your HP bar from 700+ range with a rapidfire and shiv. Rapidfire should be a safety item with relatively minimal damage gain compared to other items. The way it is right now, rapidfire has good stats and the ability to combine with shiv and speed up shiv rev-up makes it an incredibly good item and a must buy on a large majority of the ADC roster.

Amen on scarra talking about range creep (patch 8.4 introducing 200 more range on GLP active).
