An OP recently wrote a good post on how he can get frustrated when he runs groups that view cutscenes. There have been MANY posts written on LFG, and I will, with your indulgence, write just one more.

I know there is LFG in the menu. I know you can mark it and type to people. However, I think yet another advantage of a LFG would be the ability to toggle "No cutscenes" when looking for group. That way people who want the story could do it and those who don't could skip it or just have normal instances.

I think there are enough people who would want to experience both that everybody would be happy, aside from usual challenges of finding people to slot for different class roles when entering instances.

Also, the LFG could incorporate a system used in other MMORPGs where there is an item level cap for entrance, especially for hard areas, instead of just a level restriction.
