I've created a room in RaidCall so we can schedule parties to hold instances.
The idea is perfect, the only problem is gathering people to join the room.
If you do your part, the room will work. There's a formulary so you can pick a good time to hold instances. We are going to schedule instances every day and week according to the most picked time.
Lineage only works with parties, and it is hard to depend on the game room system. If you are tired of looking for a CP, this is the chance to change it.
