Dude its not market value its actual value do you not read? Artifact Crystals can be bought with NC Coins, Forgotten Books can be bought with NC Coins and Energy of Protection can be bought with NC Coins if you bought it those quantities without a battle base it still the same 1400 NC Coins...... Also you have to put in "time" I guess killing 600,000 mobs over a month is a lot as just do your clan quests a week is 16,000 mobs a week minimum which many do in a few hours on Weds after maintenance lol Never mind 2,500 mobs a day you do just keep play with your homunkulus. I mean if your not xping don't buy it you still get it free the buffs and vit so how is that bad?
Also I play CoD and Halo but your comparing Apples to Oranges, FPS games are different to MMORPG. Compare L2 to Lost Ark, WoW, Guild Wars, Diablo even is a better comparison. I play lost ark with their battle pass system that is setup in same method of free premium and premium plus and to be honest I am at end game content without spending a dime in less than 2 months and about to walk away because nothing left to no reason to even spend money on a game that i didn't even have to buy or ever invest anything but time; no connections there no one really talks to each other; guilds are just there as a reason to get certain quests done kind of dull no reason to find an active guild.
