Man, I don't want to sound like I'm constantly ragging on the suggestions here, because I'm not. I love the fact that there are actual suggestions and not just endless whining, but when I see one that I don't think will work, I've just gotta throw in an opinion.
Basically, your suggestion is going to translate to:
1) Hi, I'm new.
2) Speedrun.
Considering how often people complain about cutscenes or want to skip, or only want experience, almost everyone is going to do the following:
1) Speedrun option.
2) Find another, more efficient way to grind tomes due to the 30 myth reduction that doesn't involve cutscenes (see Brayflox HM, Wanderer's Palace, hell, even Amdapoor Keep).
3) Join the one with the bonus and attempt to harass people to skip, then act according to their reaction.
Remember, DPS may suck it up due to queue times, but tanks and healers are often going to bail because the penalty isn't severe in the least.
This ultimately is just going to hurt the people that are looking to clear it for the story even more.
