I am amazed that noone at Squeenix HQ has come up with that idea yet.

It is a major flaw in Game design if you need a exterior Program (Discord) to organize Groups for BA, but for pretty much any other type of Content you got Dutyfinder, Partyfinder and as mentioned already, the way how Queues as well as scaling works in Dalriada/Castrum in Bozja, so why should BA in Eureka be a exception?

Just because the idea on how you "queue" for it, is considered "unique" by some people (which isnt, it is just generic Portals that spawn that work just like the entry Portals in Dungeons in their overworld location. And by the way, this has already been changed once because it only used to be one Portal at first instead of multiple ones all over the Area.), doesnt mean it is useful or good.
