Agree with this thread except I think A and B rank should be like maps but you can leave S rank to be open world like they are now.
That way those massive large parties can continue their zerg fests but small parties and FC can still take part and enjoy without fighting with the bigger groups.

I think that would be a solution that works for everyone.

But most of all.... Can we please get some concrete response from the staff? ]The HP bandaid did not work and a lot of people are still feeling disappointed and left out of this system!
