Putting all (or most) of a systems warp-points into a cluster makes defense more efficient (one fleet will do). However, there is a pitfall to this strategy. If there is a way to attack them without going through one of the warp-points, several warp-points in a battle can bottle up your fleet so you do not have room to move. I've lost a fleet of Talisman dreadnaughts in such a situation. I was shocked when I lost the battle, but the replay showed my ships fighting piece mail as they wiggled their way out of a 9 warp-point cluster. Besides the 9 warp-points, a bunch of CSM V drones did not help (they just sat there blocking things up even worse).
