The announcement of Domain Invasion in unity chat is a bit unfair. Currently the best way to farm escha beads is from these fights, but a lot of the time you get the message that the unity chat is full. Since the chat is full you receive none of the announcements that the next Domain Invasion is upcoming. SE please change the system of announcement of Domain Invasions to a system that EVERYONE can see, not just those that are lucky enough to get into unity chat before it reaches its capacity.
