Why are Megaphones still a thing?

We could buy them out of the Cash Shop, or be the very unfortunate recipient of one from Gachapon.

On GMS (in order to save bandwidth?), when you went onto a map...we'll use Kerning City...you wouldn't see everyone on the Kerning City map - only those within a certain proximity. So, when you use the regular chat feature, you would only hear from those within your proximity and they could only hear you if you were in their proximity. The Megaphone was made so that everyone on the map would hear you.

On MapleLegends, the proximity feature is not present. You can hear everyone on the same map regardless of distance. This means the Megaphone is nothing more than a way to use regular chat in a bluish text in a cream-colored backdrop. They are pointless. Why are they here?

- Seriously, why are they here? Why are they still a thing? People may have found a use for them and I could be totally oblivious to it, so please let me know if I'm missing something. Otherwise, can we remove them from the game - or at least from Gachapon?
