If "ForsakenRO is ALL about CUSTOMIZATION"....Why people keep using basic gears? as Valk's manteu? Ring of Resonance (Blue Ifrit Ring)? MailBreakers? Ice Pick itself? and so on...they could make an "advanced version of those items"
As someone said "You have Unbreakable Elites Wep...add 4 Ws in it and You'll have 40% of breaking enemy armor and 28% breaking the Weapon" and the % of the mailbreak, is way low than 1 simple Ws Card not saying You can break it, so a Mailbreak [3] isn't a big deal...since You can buy any E. Wep from like 15~30 TKS and fill it with WS.
About 'Force FCP'...look at this, if more people use FCP (something that isn't a problem since a better question is "Who doesn't use FCP now?") people will buy more tickets, and giving the farmer something to work and earn some money. Also there's already so many custom and non-custom that can force people to FCP...Drill Katar? D.Warlord card? Baby Leopard,Leaf Cat,Wild Rose, Amistr Hats? Metalling card? Rouge Card (Don't know the name, but is from lhz_dun02 and strip armor), Whitesmith card? Mailbreak itself...
Not saying that...Swordbreak = Weapon breaker, list me 1 weapon of PvP that can break?; MailBreak = Armor breaker, RSX/Cornutus/FCP...problem fixed.
Not saying as if a lot of people have multiples IP...that's why they're low! if this NPC is avaible people would try it at least make it [1] ,decreasing the amount of them in the server and also increasing their value and Yea it increase the price of it, but remeber Ice Pick work as Thanatos, so a simple card of like 5~7 TKS (Skoll) can really own this item.
And indeed the GM could work in something more important BUT this NPC was here already so they took the work in removing it (if was that hard); This NPC is old, not new so won't be something to stress out imo.
And about Your teory...indeed is right, BUT You think people has that number of items? there's like 280~300 players (I think when You do '/w' and most of them are merchants lol) and even the server run about 5 years...that mean people would being crazy killing RSX/Sinx MvP all day/night to get a huge number of certain items.
Mob dropped IP[1] = 0.01% (By RSX)
Mob dropped IP[0] = 0.1 (LoD and RSX) and 15% (SinX MvP)
so as You see those drops are as same the card of the MvP itself, more like a "reward of the kill" and the slotted IP is like a thanatos card drop %...
