Please allow players an option in the UI to choose if they want to skip the dialogue when they repeat a quest. If it were an option in the U.I. (similar to the "don't show hints" option except it would be somthing to the effect of "don't show quest dialogue on repeat") then those players that enjoy reading the lore each time, may, and those that have read the several pages of conversation once can just have the quest bestowed by simply clicking repeat.
keep it the same for the first time on a quest for every new character, until they have completed the quest at least once, but after that, please?
