Yeah ^ - We have to actually plan a day and time to que in order to get a pop (as do 29s, 39s, 49s and so on) but the days we DO plan to que we get a pop. So i'd say decently successful - and the more people that join, the better chance of getting a pop! so we'd be more than happy to have you join us!
And the days that we aren't queing on your 10, you can just fool around and run dungeons, PVE, do achievements, etc. Or, in your case, go on your 19. So good luck!
