Casters vs. Unpowered Omni wheels

So I have been looking at a lot of older robots for inspiration for a new chassis design before build season and I was wondering if any veterans could tell me why we don't see casters anymore. I have seen a large number of robots with unpowered omnis, but no casters... Why do you think this is, becase from where I'm standing...

Casters
Pros:
  • Self Contained
  • Pre Assembled
  • Bolt and Go Simple
  • Smooth Ride
Cons:
  • Have a "Direction" that must be overcome
  • Cannot be Powered
