Dunno if anything similar was suggested.
Basically the idea is to add in a NPC that exchanges a set of items for newer/promotional headgears.
http://elariaro.com/...Headgear_Quests (disregard the quest itself, just refer to the headgear list).
http://woon-ro.com/w...Headgear_Quests
Aside from the listed misc items, each headgear would also require a special item dropped only from MVPs.
This would make some of the miscellaneous drops useful while also add more value to hunting low level MVPs.
So for instance, to create Autumn Leaves you would need:
- 148,090 Zeny
- 10 Blue Herb
- 5 Deadly Noxious Herb
- 20 Green Herb
- 25 Red Herb
- 5 White Herb
- 30 Yellow Herb
- + silver token [e.g. dropped from eddga at 30% chance]
The lists above are just an example of potential headgears and required items. There are also some "popular" hats missing like: I Love China, Well-chewed Pencil etc.
I have seen this kind of system/npc on other servers and it worked really well. It had a good impact on the economy since a lot of "useless" items entered the market.
