Lux items in shops??? You, sir (madame?), have had it easy.
Try the "no NPC shops for you, sucker except the basic low lvl stuff" type of economy, with PC CRAFTED higher grades, as the drop rate of a full item is 1 to gazillion (not even TOP only) economy, with % based QUESTS to get the (a) key materials, (b) recepies (Oh... I'm sorry... did you want a MAJESTIC recepie? upsi... you got Dark crystal!) and throw in the 60% succes rate on a CRAFT (x weeks of questing, let's say you got lucky and got the mats and recepies, getting the basic materials together... You find a dwarf, get everything, click... FAILURE! No items for you. Have a nice day! Come again.).
To add insult to injury, throw in a huge amount of money sinks (special "shots" for weapons, potions, teleports, overpriced basic equipment etc.) and what do you end up with? LINEAGE2!
Sorry, but if I can come in "+" with JUST grind I'll be more then happy. I can buy almost everything in NPC shops? OMG! I'M IN!!!
I will not get into details just how much of the money grinder L2 is, how the economy is <add any random curse>, how almost everyone needs to have crafter/spoiler alt to just stay alive and be able to afford the minimum. After 2+ years of such schooling Aion seems like a sunday school with Santa to me.
