I'm on my tablet heading to work right now, so I can't post the images, but I ran 3 hotbars then. My 2 PvE ones, and a third one just for PvP skills, and with duplicate PvE skills on it. Had I not had duplicates (even on PvE hotbar 2), and if I replaced things I just didn't use at all (Spread Shot, Turret Retrieval, etc.) I could easily fit the 6 PvP skills I used within my 2 PvE hotbars (I didn't bother with the TP refresh, I had turrets for that back then).
In the case of melees, I had room to spare too.
