my suggestion

my suggestion is very simple and theres reason on it

1.Add a reverse equip Npc.
(The chance to get a reverse item is like 0.01%) thats my thought.
if your willing to add the reverse equip npc. try set the price high or who so whatever. or use maple leaf.

2.permament cash item, or extend till it wont expire easily
(people waste something to buy cash item e.g. fishing rod for 90 days is kinda a little waste i suggest that the expire date should be like 2036 or whatever. as long as it wont expire easilly it would be good.

3.random timing boss event(fake boss event)
( i know henesys already got one but what i want to ask is fake boss but hard e.g. pink bean and other stuff)

Ontop theres a poll (suggestion) for boss if GM are willing to add on option 3

If cash items doesn't expire, you will see people spamming on cash, and cash items, resulting in nobody farming for mesoes and all that, if that would really happen, why not you go play a high rate server? Where everyone trains till a point, and afk 24/7? Please use your brain to think before suggesting. Please seriously.
