Haven't you realize after all these years clicking the dam buttons, that if there is a level difference of 5 between the party members you have XP penalty? Then why i see on party matching window things like: "spezion w/fm" 90-100 "istina normal" 97-104 PS Have you also notice the decrease in drops if +3 or higher from boss? Have you? Or you go at 100lvl to kill Istina for XP?
and what must ppl do with 100lvl main and 100lvl sub? sit in town and dont do anything?... they go just to be done.. and btw even lower drop means a chance of drop... saw istina ring droping when all in pt was 99-101
