If they were to introduce a level boosting option, I think it most definitely should not be to get to max level or close max level. And it most certainly should not be introduced so early. We aren't even on our second expansion yet. WoW didn't even introduce theirs until after how many expansions? If anything, increase the amount of experience you get during low levels so people still get that low level experience, but leveling gets sped up significantly (but I don't suggest this for a long while yet).
If people are so concerned about it taking so long to do the story to get to other content, even though it pains me to say it.... Somehow make it so people can skip the story it it's not something they are interested in? I love the story so much, but my mother is one of those people who's not interested in the story and thinks it's an annoyance... So I totally understand where people are coming from.
