New characters will actually benefit the most from running the main story, since Yoshida recently said that xp rewards will be doubling for the main story quests, and that new players will get priority queue into dungeons they haven't completed yet. With the roulette bonus, challenge logs, job logs, and now this huge xp increase, leveling to 50 will be a breeze. Add to this, all those main story quests we all got zero xp for, new players will get double xp for, perhaps letting them level to 51-52 easily just getting done with 2.55. In addition, Yoshida mentioned 'powerful weapons' as rewards - perhaps they will bump the lvl 45-50 AF to be the myth gear (i90), which would make a lot of sense. So, in essence, I kind of envy these new players (and may make an alt myself just for fun and to have 1 of each clan of Au Ra) ^^
