Though I am not in Beta, I have tested for other games in the past and I always find the most satisfying and also infuriating thing is Developer feedback.
When it happens it moves the game forward, they can ask for areas to be tested and people will test those areas and provide specific feedback and everyone wins.
When devs are silent you end up feeling why bother my input isn't wanted so you stop and the game suffers.
So much Kudos to Devs responding may it continue up to and more importantly beyond launch
