Rapid Fire Cannon

This item seems too powerful to me. It does so many good things and isn't even the most expensive item. Let's see...

Good crit chance Good attack speed Good movespeed Big bonus damage Big increase in range which is especially powerful given how important of a stat range is and the attack range up is exclusive to this item. So everyone that wants to get the more range doesn't even have an alternative.

And as if all this great stuff weren't enough, it synergizes really well with almost every good 1st adc item to the point where it's pretty much the goto 2nd adc item almost always and on almost every adc. Let's take a look at these more closely:

1st, the extra range and extra movespeed are incredibly good with anything, so the rest of this is kinda just icy on the cake, but it's some strong icing.

Infinity edge: Gives a huge increase in damage and crit damage. So the increase in crit chance and attack speed really up your dps. Bloodthirster: Another big ad item. So again, crit and attack speed are going to be the stats that give you more dps if you have this. Statikk Shiv: This is a first item for Vayne users. And it synergizes very poorly with Rapid Fire Cannon tbh and yet Vayne's still always seem to have to get a Rapid Fire Cannon as their 2nd item anyways. This is what really shows that Rapid Fire Cannon is so strong if it's the best choice even when it shouldn't be that good in the given situation. Blade of the Ruined King: After the extra damage from its passive, this is pretty much effectively another big ad item. So again, the crit chance and attack speed will increase your dps more. But this one maybe not as much since the bonus damage doesn't crit, but that's made up for by the crazy chasing or kiting potential that you get from the big range + a slow.

Let's look at some alternatives:

Phantom Dancer: Since you need that crit/attack speed item 2nd, this seems good, right? But it gives similar stats to the Rapid Fire Cannon, but without the really strong range increase. So it's kinda just worse unless you think a tiny bit more movespeed can outweigh tons more range, which it can't since you don't can just attack from further away with Rapid Fire Cannon so it's probably even harder for them to get away alive.

Statikk Shiv: Another item with similar stats but again, a way worse active. It's like the damage but without that op range again, thus not being op.

So really, Rapid Fire Cannon just seems like the only best option for a 2nd item on almost every adc right now.

Unless there's something wrong with it that I've yet to realize; maybe someone could point that out to me.
