Guild Wars 2

Just getting started in pvp, and I am trying to figure out the node states. If an enemy comes into a node you are holding, do you lose the node even if you hold out? Should a defender focus on intercepting the FPA before they get to the node.

White = Neutral (no points gained for either teams)
Color = Captured (1 point per tick)

Enemy entering captured node: Node will remain captured untill you are off it for 4 seconds whilst he is on it. (4×1 second also does the trick)

Decap takes 4 seconds
Cap takes 10 seconds

A defender should focus on staying alive and dealing some dps until backup arrives, if he can’t defeat the enemy alone.

Capping points has 1 speed, 2-5 players don’t increase capture time.
So only let 1 player cap, the others run off to other targets
