Saints are a huge problem with forts, for example the other day my guild lost a fort because a group of 8+ saints grouped up top being unattackable, then suddenly all got on the same guild tag and rushed the flag taking it from us before we could react. Going afk overnight to get saint isn't very difficult.

I also hate the changes that made tower hp extremely low, now you have to be attentive to the flag at all times or you lose it within 5 seconds. You can't even talk in guild chat anymore or relax when the tower is calm because of how fast it changes. IMO respawn points should just be more difficult and the hp should be raised.

"Choke points" need to be removed from towers as well, people should not be able to block stairs or doorways because it takes no skill and is not fun at all, theoretically a tower could be untakable if 3 people manage to time their respawns so that the stairs are never unblocked.

Guild Wars 2, attacking a keep or fort filled with siege is extremely difficult due to the height advantage that players get by building trebuchets on high points or arrow cart spam. given equal sized armies, the defenders should win.

However, the main strategy used in gw2 is just zerging random towers and forts rather than defending what you have. If attacking was easier than defending, then people would not be able to defend and would just keep capturing, an example was deadwood fort prior to the fix a week after, it kept changing every minute or two, no one could hold it.
