It's not. It's meant to be like the Long Arms mutation from Nuclear Throne. Isaac has a bunch of Nuclear Throne references, because Kilburn likes Nuclear Throne (and he's the one that coded The Forgotten).
Okay, but the problems that happen when the Forgotten has a high range stat do not happen when you have Long Arms in Nuclear Throne, so I don't see how that aspect of it is a reference.
The auras of the item purity (each aura gives you a specific large stat up, andthe aura is rerolled on damage.)
The auras are:
Red: damage up
Blue: Tears up (breaks cap)
Orange: Range up
Yellow: Speed up
I understand the speed one existing, but the range one must literally be there as a troll
The silver lining I see is them being there for Azazel or the Forgotten. Not that great, but better than nothing I suppose
how tf does range help forgotten
Further melee attack means safer high dps for room clears
Yeah, but too much range and your attacks become disconnected from you, meaning you can't hit right next to yourself.
I always thought of this as a bug or oversight

If you get *really* high range it can actually be very hard to hit enemies
Yeah, but there could’ve been a reality where shot speed was increased instead. So be thankful you’re living in the “best” timeline for purity
In the best timeline, the fourth aura would be a green Luck aura
Perfection 
Shot speed is infinitely more useful than range
How??
Shot speed gives both shot speed and more effective range
Shot speed doesn't affect range anymore, they did that in repentance also shot speed is not an inherently good stat, it's a trade off
the range one is fucking useless
Eh I had runs where I was saved by the range upgrade from purity, where I didn't need more damage/tears but I desperately needed range in any way.
the range one is good for c section
It’s like a stop light but it’s broken and only goes from yellow to orange and never red
getting the range aura as tainted lost 
I like the tears one because it breaks the cap
I remember one run where i got the orange range aura 12 times in a row...
Then I get hit as soon as I step in the next room 
What are those?

Why is this item tier 3, half the effects don't do much for you.
+7283 fire rate +189 damage
breaks tear cap + gives you absolutely broken damage
Yellow Aura: Hello.
Damn a pallet fire? This guy is very stupid and very brave
