The server you played probably have closed because of rising prices and this game is following the same path, so I said only survive who put IM points, but as you said, developers need to be paid and the game has to make profit. Let's sit down and see the price of the items at the beginning of next year.
First of all, don't start false rumors by wrong assumptions you're making about the server closings in the past.
I am coming from the same official closed EU servers like sigeel. The real reason why the servers of SEA and EU closed finally at March and April 2014 was the statement of Gravity Korea to drop the development for this game. And these publishers saw no sense in continuing their services based on that decision. And this is the reason why they closed. This server is the only one which had enough trust in us - the players - when there only were a handful of them playing here in April 2014. Then all the EU players migrated to here (like myself) and nowadays, with a taking over the source codes from Gravity Korea, WarpPortal is able to develop the game again. The Arcadia Update and a large amount of fixed over the last year is the proof. And the community is still growing like Apocryphos already said.
The game has mostly changed from a pay-2-win environment to a pay-2-speedup environment. And we are still working on it. If you don't have the time or the patience to farm and grind - which is the main purpose of this game - you need to invest real cash to speedup everything, but you aren't forced to.
There are several ways to get gold. One more is to play the Hunter G. dailies to sell the Hunter G. capsules around 30~40 gold each. Also you can do the Guild dailies. From Level 40+ there is a rare chance to get IS, RIS or Soulcraft Randomizers. It can not be used as main source, but it's an additional for everyone who loves doing guild dailies. Also you can get bags of gold and silver coins by doing them.
Finally we don't need to sit down and see the prices, because the overall pricing is the same since 2014 and it won't change. If you need to buy IM items with cash you might want to participate in one of the IM sales we have on a regular base (the next one will definitely be the Black Friday Sale in November).
