Ugh level 99 is such a pain!!!

I am trying to get to level 99 ASAP, but the process is soooo long! I am level 84 because I got two levels today abusing the crap out of Blitz modes. I want to get to 99 so I can take advantage of the "All-Star Mode" when the DLC finally releases. If anyone reads this and would like to join me for some Blitz, I would more than happily join. I am happy to say I got to wave 145 by my self on Sudden Death Blitz earlier today, so some real teammates would be welcomed. Thanks!
