This is the strat I've come up with for this map. You wanna run 3 bunkers, and 2 DPS roamers. At least two of the bunkers have to be Guardian (specifically with this build, http://gw2skills.net...0lwLbOuuk5s Y8B although any tweaks you may want to suggest are welcome.) and the two guardians running this sit on the orb spawn/run the orb. The third bunker's job is to switch between several points, trying to switch it up every 2 orb captures or so, and the roamers are there to provide support for the runners and also clear the way for the point bunker to do their thing. After you hold a single point for too long a smart team is gonna realize if they decap that, then they can stop your point influx, so that's why it's essential to keep switching it up so your point bunker doesn't get zerged out. Avoidance works a lot better than simply delaying the inevitable.
The reason I suggest you use 2 bunker guardians on the orb spawn is based primarily around the recent buff to the staff. If you have 2 guardians use Empower, that's 24 stacks of might for the both of them. This sets their attack to about 3600 with a cleric's jewel, and with the extra boon and might duration from your runes and traits, those 24 stacks lasts for 15 seconds. With the reduced 2h trait, Empower is on a 16 second CD. These together allow the two bunkers to keep near infinite 24 stacks of might (25 if they pop Save Yourselves.) The idea is to have a nearly unkillable duo while also dealing significant damage thanks to so much might. (And really high Retaliation damage.)
And finally, when you get down to the really big mindgames, all 3 of the bunkers should be able to solo hold a point with this build, so if the opposing team decides to just zerg the orb spawn down so hard that even your bunker duo and the roamers can't handle it, you can just switch it up to double or triple capping all three points and focus on that since you probably have a pretty early lead thanks to how you handled the orbs earlier in the game.
If you guys have any suggestions on how to change this build, or the strategy in general feel free to post.
