I used to play on this server quite a bit over a year ago, but I quit around this time last year. I'm going to start playing again and was wondering if anyone could give me a rundown of what's changed, thanks.
I'm not a super high level (120) and am a new player (1 month of so). But I recommend glancing threw the source updates from the past year to get updated on content changes (for example we have HT now, and the new Ninja Castle). To get updated on prices (as I'm sure they have increased) here is a price range table on some common items by @MysticalSt4r: https://royals.ms/forum/threads/p-c-on-scrolls.112936/ . To get down into community changes and more, I recommended looking for a nice guild that might answer the questions you have. Although, I think the best way to know what changed is to get get into the game and explore it for yourself.
Right now the biggest things you'll notice is boat rides, no more FM button (there is a lounge button though), no APQ, no character deletion, and no EXP loss on death. As for whats changed otherwise, some small changes to skills, gach items for ITCG changed a bit (Sila made a guide somewhere). You'll probably notice some things have gone up in price (however most everything has), and leeching is pretty popular. But, the game is still here.
