Because those tickets are sitting around for months!
We all have tickets stil there from beta and gamma versions, that haven't been looked at at all.
So many among us experienced, that this forum is the better way to communicate with the devs, as it seems they look here and even fix stuff mentioned here, faster than through tickets.
That's why.
(as a sidenote, when you look into the rare-thread, you'll notice many of us already raised a ticket about this issue parallel to mentioniing it here)
And this "you know better than the devs?" statement is just childish.
I couldn't be bothered responding to post like that...fortunately you said exactly what I wanted to say. 1+ rep for you
