I am asking myself in regard of all the bugs I read about and all the issues are posted here and within the issue tracker, how the test setup could be adjusted to prevent the current situation, we're in.
Beside focussing on the FC, a regression test for the 'legacy' parts of the game needs to be done under 'realistic' conditions. The server and IT setup/architecture should mirror the production environment (not 1:1, but if you have several servers for different roles, this needs to be respected). And for sure you need some mechanic to put load / pressure on the system. Best would be by simulation of players / commanders (are there any bots for E : D which could perhaps be used for such purpose?).
But writing my 2 cents I know exactly, that even the best test setup would not find you all the flaws and issues which could occur in reality. But they could be reduced - especially such, which affect nearly all Commanders.
I am really hoping, that FD will hold an internal lessons learned on this episode and - especially, as
@FlySwat wrote - with Odyssey on the horizon, take the learnings to the tests of the new DLC.
Fly and stay safe
