People wont simply MPK for the fun of it in most cases, there has to be an underlying reason for it. When one of the stronger notorious monster spawns in most cases there are 4-5 other linkshells at its location and prepared to fight. Chances are they spent hours camping it because the spawn conditions remain random to a certain extent. My suggestion is that you look at a person's reason to MPK as well as modify certain errors which I’m sure occur.
There is a near unlimited demand for 'the best' gear, but the supply is so low. It’s simply not reasonable to assume that there are still only one or two groups of people out at hyper notorious monsters day after day. When someone else gets the claim on the monster it’s hard to just be happy for them. If a group continues to get the claim day, after day, after day, jealousy will be sparked in even the most reasonable people, some may even decided they need to MPK to have their chance at the monster. This is part of the reason i think forced spawn monsters were the best change made so far in this game. Suggestion: Make monsters more available to kill. Make the items they drop, that cannot be sold, more probable to obtain. Make more items EXclusive
A massive amount of frustration if fueled by a player's zeal. It is not a mystery who the persons who engage in RMT are on my server. They monopolize, steal, and ruin our economy. Hyperinflation on these items is just a small part though. A person has a desire to have good gear, there is a sense of accomplishment that comes with it, so when these items they want can no longer be obtained by gil exchange (due to a lack of their own funds beating the inflation), or by hunting, a person can be forced to either MPK or purchase the items or gil from these people who engage in RMT. The times they do claim it, the item they seek will not drop. Suggestion: Have an alternative way for a person to obtain any item. If there is another way, there will be less MPK.
Players are currently able to claim a monster being fought when the name becomes yellow for a fraction of a second. The persons previously fighting it will be killed if the new player’s presence is not made painfully aware to the monster. When the first group is dead, they will seek to right this wrong, and a GM currently has no power to act when a mob is taken in this way. They will likely MPK if they cannot steal it back, and they are the ones punished if a GM is called. Suggestion: A monster should not go unclaimed while a person is fighting it, regardless of death, or being dropped from a party with hate.
Currently if a Monk class player joins a Kirin fight to use their Chi-blast ability, and leaves the fight, Kirin will remain red for them, not in a party, and it will continue to attack other persons until the Monk has either been killed, or hit enough that Kirin no longer attacks him. The monster regains health, and people will continue to die. Suggestion: Claim of the monster should remain with the greatest number of people engaged, not the person with dominant 'hate'.
I know I dont speak for everyone, but these are among the changes I would like to see available, and preferably soon.
Thank you for your time.
