Let's look at 6 years age SWTOR:
Illum is a FUBAR waiting to happen.
Illum fix number one, 6 weeks in. Illum fix number two 12 weeks in. Then the enter planet just shut down as a war ground.
Let us not foreot the Warlard boxes.
There was no Legacy
You played Republic or Empire not both on the same server.
BioWare decided which server your guild would located on prior to release. If you decided its not the planet you want, ( Guild rivalries, RP server, whatever) your members could end up on the wrong server.
SO you can take those Rose colored glasses off now
And Im sure there are a few things I missed from 6 years ago
