i doubt they will fix them in new expansion also lol..Always been rolling people bro <3 .
There is no such a thing "duped items", ofcurse there are some duped items in old servers like ares/dies/xigenon etc..
But in servers like europa,cwest,helios,ionia etc..(the ones that created on last 6-6 and half years)
There aren't any duped items in here, all those +10's etc.. was sold by K2 gms if thats what you call duped items.
About jail for nothing, I've heard that half of europa (if not more) got jailed for no reason, but we hadn't this bug on usko.
Yes, some people got jailed by mistake but it was just because of their anti viruses and it was "some" people, not the entire server.
If you keep changing your password now and then, you won't get hacked.
quests...we gotta wait for the new expansion, I doubt they'll fix anything before.
