Just something to keep in mind though... This almost certainly will result in more people using LL overall. At this price point you would think it wouldn't be many, but Disney did not launch this with the intent of selling a couple dozen a day. They will make it work.
And if more people are using LL's overall, that means either longer wait times in the LL's (probably unacceptable given the price tag for premier), or other adjustments will be made to the "standard" multi pass. Things like fewer sold (Disney won't like that) or fewer passes available during the day. They could also add LL to even more attractions that don't need it, just to they can increase the number of passes available.
I don't pretend to know exactly what the impact will be, but there will be an impact.
