Guild Wars 2

I don’t know how this suggestion sits with people more experienced than me in sPvP, I only recently started playing it, but to me the 3 control points with 5 people is not working well overall.

My suggestions would be to:

1) A team can only score points when it has at least two active control points. This would have two great benefits:
1.1) A team that is losing, or was unbalanced or had players that quit and are lagging behind in points can completely turn the game back around even if the other team was about to win by holding two points, essentially making the other team not score from control points at all.
1.2) People would actually sit and defend, instead of just run around in a poorly organized fashion to hold 3 points.

2) Holding a third point would award more score, but would also make you more vulnerable to losing two control points yourself – which now awards no points at all, so it´s a more significant choice than the current dynamic right now of swaping control points non stop.

Not a good idea. We already have to much bunker builds. If they did what you proposed, that would lead to every team having at least 2 bunkers on their team. And once you have captured the point with bunker on it, we know how difficult is to get it back.
Also, on legacy map a lot of times happens that neither team captures the mid point through the entire game.
