Shorter Cooldown on Fleet pass
If they don't shorten the cooldown on the fleet pass, easier way to get to flashpoints instead of going to the planets spaceport, going to the dock, getting on your ship, fly to the fleet, get off your ship, get past the dock, and then make your way to the flashpoint.

Personal preference, make khem val less over reaching, I always click on him when I am trying to click on a resource node.
