Vehicle sucks.
But at least with IS Boxer, the slaves follow the master for 90% of the quests, with just the normal FTL Follow Me.
And even if they don't follow, the 1, 2, 3, 4 etc auto assist the active toon, and press the same button number.

I'd rather play a Warlock, Druid or Shaman, then a Tank, Helicopter or Knight.
