I'm not dissatisfied with the spawn locations/drives ~ mostly because I've got a whole bunch of kids in the house. I have the luxury of being able to say "hey, want to drive me to the base? Kill anything that gets in front of you," and they'll gladly do it. Or I can do dishes/laundry on the drive (if a hill or tree doesn't stop me).
But the SB ~ man, the SB piece sucks. I went to film last time some putzwad sat in the SB while our base was getting slammed. I didn't up in time to record it. He towered out (or auto-towered) with his kills before I recorded. So it's not just enemy's that sit in the SB, it's your own guys, too... who sit in it afk & rack up proxi kills. Putzwads.
A name above the guns would be enough to run those putzwads through the reamer a few times when they do crap like that.
