Kinda confuse as they uses orbs as their 2nd currency. Instead of using gold to buy items on trading, instead they use orbs as payment.

Are orbs really that important?

Orbs = gold. It's great to use system like that, because you don't need to make gold sinks, like repair costs in WoW etc.

yes, the path of exile orbs is equal the game gold, you can see upitems site what you know. Many items we can use it.

Gold has several consequences in an action RPG setting:

Gold Sinks: Games that use gold incur high inflation unless they have sufficient gold sinks in the form of mandatory expenses such as item repairs, paying to revive characters or continuously buying potions. These sinks are generally an unnecessary obligation and can be frustrating if a player is low on gold.

Gold Farmers: Online RPGs often get infested by gold farmers who play the game to accumulate large quantities of gold that are then sold to other players. If gold is the main currency, it’s very simple to perform gold-accumulating tasks to supply the secondary market.

Wealth Determinism: Earning a steady quantity of gold from monsters killed helps to re-enforce the treadmill feeling that many online RPGs suffer. People’s net worth in gold is directly proportional to the amount of time they have invested playing. This highly linear wealth gain can cause a sense of disillusionment when trying to save up a large amount of gold for a purchase – it’s apparent to the player how long it’s going to take to grind for it.
Trade Parity: With a common gold currency, it’s easy for players to know and demand the current market value for an item. If the trade occurs at a value that differs from the current perceived market value, then one of the players feels that they got ripped off.
