It would help us know what to bother reporting/reviewing in-depth if we had more frequent updates. Maybe I'm just used to Path of Exile's nearly-daily news posts, but as a beta tester it's...been a little while since we heard from you guys.
At the very least, the Known Issues post in the bug forum ought to see (nearly) daily updates. Copy and paste from reported bugs that you've logged. Easy-peasy.
As for non-bugfiix, feedback, we have no idea which systems you're reworking if any.
Thanks!
