It's a great game and I've around 15k hours in it and around £1200 spent on the pearl shop over the 2 years. Most of it is convenience items, I've only spent like £100 on artisan memories (kinda p2w) but I coudl've achieved everything I have without it, it's just I got frustrated one night and decided to accelerate things a little, let's put it this way. Most of the money I spent in the game is on outfits, costumes, pets and some convenience items (weight, inventory space). You could try to snipe these off the Market Place using in game silver but it's not easy. Btw, if you think this is anything like WoW, think again. Completely different game and the progression is a marathon. It's a long journey and there's no shortcuts. You can't get carried in a Heroic Raid and get gear. You have to earn it your way and it's a grind. I don't even know how best to explain it. If you do get into it, be prepared to be overwhelmed.
