I would also call you the best tank on the imperial side. THERE I SAID IT.
But anyway, yeah, I think it goes in phases? Sometimes the solo queue is death in either faction. And yes, imp-side seems to have a lot of new 50s coming out of the woodwork, lately. It's awesome! I hope that they don't get too discouraged, and keep at it. I used to hate 50s PvP, and it took me months to love it.
