The idea that you (Devs) allowed the player base to test stuff in theory was excellent. It was unfortunate it was PC only, but I get you would have to go through hoops for console(s)
A few of my clan members, some FTP told me it was pointless, due to following reasons:
No incentive to test stuff as had to grind /play to earn new vehicles, they were not unlocked by default, the XP gain was too low, it would take 2 days even with premium BP to grind one vehicle.
The fact that people had to spend real money / gold to unlock the premium vehicles, mean a lot of them are FTP and could not test other than in practice.
Feedback and comms were very dispersed and not easy to track down if someone had mentioned something or not.
I work in SWD and here are a few suggestions for Gaijin, Devs if you want effective free testers.
Next time:
Offer some silver/ Gold to anyone who participated
Unlock all vehicles or give people gold to buy the vehicles or levels to test certain vehicles
Have a dedicated CBR label for all Test server feedback or have a new Test Server discord channel.
(So any minor fixes and retesting could be communicated to these people, kind enough to spare their time testing the game)
So even though test server was granted, it wasn’t delivered in optimum way imho
