60 or 70 bracket activity

Hey guys,

Im quite new here and i wanted to get myself into twinking. Now before i get fully invested id like to know if it is any active, mostly bg wise.
I quite as 19 and it seemed active, but queing as 60 dk was "unavailable". So, are any of the brackets active and worth it?

Thanks in advance!

I recently started playing on 70-79 from quite a long break. It's the most popular twink bracket on Warmane, so don't hesitate and make a character :P
