Is Baldesian Arsenal discord a mistake?

[Akonyl]

IF the people are not invite to the discord, they can basically never get in BA as a party, net alone train and get crystal to boost their equipment.

I don't know about your server/datacenter, but when I've been in BA groups, the people in the group almost always shout a link to the discord in eureka, asking that people join the discord if they want to get in on organized BA runs. There are multiple public discords out there, running groups ranging from newbie-friendly fragment farms + prog learning, to clear attempts. If you look around, you should be able to find one for your DC pretty easily.
