Crystalline conflict is a well-balanced, rather fun PvP activity in this game, the problem with it is that it's FORCED solo-only play in the way that processes your series milestones.
So a little while ago at the logical European data center, some friends and I could finally scrounge together about 20 people to try out a group-based queue for Crystalline conflict, where we used discord channels to group up once we were inside the instance.
It was the most fun player-vs-player game we had in a long while.
After a while, we also did a small tournament using custom matches.
I here-humbly request to add 2 duties to the PVP duty finder:
Crystalline conflict (Group Ranked match) and Crystalline conflict (group Casual match) where you can queue with a group of 1 to 5 people to be matched with other groups of 1 to 5 people in 2 teams of 5 people to compete in crystalline conflict.
