Multiblocks sounds like you are getting the worst case scenario. On the upside it takes me ~6 hours to get a level questing. Soooooo start winning some games and everything should be good to go!

Seriously though this AV leveling is something I am really excited to try out. If you have level 80's that can go into AV with lowbies then it should be awesome. I would think alone you can guarantee at least one tower being destroyed.
