what about make 2 diferent looting systems? one for normal party and one for raids.... there is already switch onto targetin wich to me seems great for when doing stuff with alot people like Behest, and other when doing leve party with very short crew.So i think a switch for diferent kind of lotting systems would work great.
One that allow people to set wich items are unwanted or what they want/need from the treasure pool when killin a certain kind of monster for exp. so our pockets dont get filled with trash.... cause face it... we cant look everytime we kill bunch of monsters when killin fast for exp/sp, and our pockets often get full of things we dont even wish but others may...
And the other Mode of loting that be only available for raids or NM drops where ONLY the party leader decides who get each drop, i think if you have a party leader is cause everyone trusth on him, after all thats why he/she the leader.
