lol...not a lot. They both have their own accounts, so it's just the random time here and there when they want to take a 32 out for a spin.
I've noticed more and more that I just can't pick what to level, and end up leveling nothing since I go off and do a raid or something that requires me to use my maxed gear. I also don't have a regular crew, so I pretty much spend all week looking for pugs to just finish my weekly tasks.
edit:
Whew...I feel a bit better now. I still know that I waste a bunch of time leveling up just one piece at a time since everything I want to level is a primary.
