Let me start by saying I played FFXI for 1 and 1/2 years, and left for WoW because of gilsellers, terrible prices at AH, and knowing that eventually my poor player would be subject to another poor player's crap.
YAY to SE for listening, and I am fully back in the game, as I have always loved FF.
That said, here are my thoughts,
I agree with Tomokutherdm. Start there.
Suggestion: AoE attacks by mobs (such as the description listed below with the scorpion) needs help. I don't agree with getting rid of AoE, I do agree that the innocent bystander pt should not be left to rot. My thought, if the mob has been aggro'd and is in combat with another party and casts an AoE, the AoE affects it's current party, not those in the area minding their own business.
Suggestion: Those who want to use a star system or mark other players publically would only cause more issues in my opinion. As fun as PVP can be, doing it in response to bad acts can turn hostile. Yes, it may kill off MPK, but would only cause more trouble elsewhere. As SE can't possibly monitor every drop all the time, consistantly and randomly monitoring common and semi-common area's for both MPK AND gil sellers (invisably, becoming viewable when neccessary) would be a huge help. The honest remain honest, the jerks get punished.
Suggestion: MPK isn't the only problem. Though a big one, and there are many great suggestions and I am glad to see it attacked, I think gil selling should be the next big attack. It throws the online economy out of wack and makes it very difficult for the rest of the community.
THANK YOU SO MUCH SE FOR COMING BY AND ASKING FOR OUR OPINION. I hope this trend continues as you have stated you would like to do.
Always,
Seras Victoria
