1.open arena ,so low fame player can ks for fame,due to party leader will always those who low fame even they say relog.
2.boost fame rate for below 75000 fame so that low fame player can chase the fame ,decrease the rate of low fame player feel bored and quit game.
3.boost fame rate for full party job (eg.akkan have 6 job,if 6 job also in 1 party will increase 30% fame rate,so gunner and shadow can join the pt.)
4.if one party have member fame below 75000,fame increase 5% fame rate for each member,maximum 25%.
All above suggestion is for encourge more player join for pk,not just specify player will be invite to join the party.
