A good idea by Coin3

Well, eventually there are going to be more area, one being an underwater area. What should happen is some areas like the underwater area would be hard for people to stay in unless you have a special thing. People with the water element could go in the water as long as they want, no cost. But the other elements cant, so they could go to the store and buy an item allowing them in the certain area for an amount of time or an all time pass for a lot of money.
And also, if you're the fire element you would need a specialized version of that item which would cost more.
All the other areas based on an element used would be like this.
Well there, that's it.

i more or less agree with this concept, specialised area's could add an extra layer of depth to the game

That would in fact be good, but I'm worried about how bad the coding would be for that. It would also make for more interesting grind spots for certain elements, which would disperse the population slightly, but that could be either good or bad.

It would actually be pretty easy to code, that's not an issue. My issue is that I don't like the idea of limiting players based on the element they choose. I do like the concept, but I think all players should be able to access all areas without limitation, and without having to grind for gold to buy items for said places. I'd be more in favor of boosting certain stats for players of the corresponding element. For example, water elementals move faster underwater, fire elementals gain attack power in the volcano, etc. What do you think of that as an alternative?

Wow, I like that better than my idea.
Yet another changed outcome by... Nighthawk!

sounds good

Yep. Sounds like a good idea to me. What about earth and air elements?

Earth could gain Def when it's underground, and Air could gain Dex/Wis (Faster HP/SP regen) in high places.

Works for me

Great!

hmmm , how about air moves and jumps higher when in high places?
