Gil cost for Teleport - Throwing money up in the air while casting?

[RaphaelDDL]

Imagine that your character is casting a magic and throwing money up in the air.. Does not make sense.

I know it's a thing to make people spend their gil (gil sink) but that does not make sense, since it's like the same of costing gil to cast a spell like Ruin I or something. I'm not a Samurai to spend Gil on skills (Throw Gil).

If they want to make Teleport cost something, should've implement something more plausible, like Ragnarok Online's Warp Portal skill, which costs a Blue Gem (bought on store) to actually being able to cast.

This could add some economy as well, since that item for teleporting could be also Mined or crafted.
I know simply spending gil rather than having an item on inventory is a lot better but it does not make any sense if you look closely.

What you guys think?
