It is because alot of players who had already seen the MSQ were forcing new players to skip thier scenes, kicking the ones who didnt for being "afk", Yelling at first timers to hurry up and watch them in the inn!!,Being total jerks at the end with snide comments like your welcome for the carry or my shoulders are killin me from carrying your useless self as they were leaving and in general being utter reprehensible tools toward thier fellow players that this was enacted.
Square in thier infinite grace raised the ending rewards by ALOT to compensate. Double the xp gil and tome bonus at the end of Meridianium(Still think they should match Praes bonus at this point cause I can see players eating 30s when it comes to xp simply due to the skyrocket values needed to level in ShB, and players are nothing if not in rush to the end mindset when it comes to numbers), and Triple the XP at the end of Praetorium to compensate.
It was and is a fair middle ground new players get to experience the end of ARRs actual story the way it was meant to be experienced and others get compensated for their time. No amount of pissing and moaning about it is ever going to change that decision so might as well do one of two things either deal with it like others have, whine and moan in party chat like most have, be cheerful for more new players like a few have, or just dont do it if you dont want to have to see the scenes again like a very few have.
