I sometimes play dungeons because I enjoy running them with random people. I have this option to do that at anytime. I cannot do this with BCoB.
I would love to play with my static party and then help my free company.

That being said, I don't know how a loot lockout would work exactly. I mean I understand where this is going, but you know what it would lead too. An infinite selling amount.

I personally like the way it is right now. It gives players the opportunity to improve their skills and use better teamwork. To me, in my own opinion, that is how this game should be played. We can clear the first 4 floors no problem now and we did it with practice, perseverance and determination. I know other people can as well without relying too heavily on people who have already beat it to help them through it.
