Guild Wars 2

Can anyone tell me how to break into Garrssion’s lord room if there’s having unlimit super arrow carts/seiges and the full oppsite zerg inside?

Find new tactics.

Unless you can over power them to take it, your only real option is war of attrition. Attack Garrison normally, but with the intent to kill siege. Set up counter siege to damage as much as you can to force them to use the supply in the keep. If you can run them out of supply and cut the incoming yaks off, it comes down to ZvZ.

Or less likely to work, you can try the 10+ golem rush. Stay busy and get them to hit either hills or bay. Around when they get in outer gate, golem rush water gate Garrison. If you do it fast enough and they didn’t scout you, you might be able to pull it off. The draw back to this is they will normally choose to defend Garrison over taking one of your keeps. This is a problem because if you fail, you now didn’t take garrison and have a banged up keep. Or if they only send enough back to keep you from capping, they could take your keep and come back to defend. High risk, high reward.

Another option is to have your other commanders on other maps hit high profile objectives like T3 keeps to pull the enemy force off your map for enough time for you to make a push. IF you have been consistently hitting garrison this won’t normally work and if they have queued maps this probably won’t work.

Edit: I said 10+ to be humble but if you really want Garrison don’t be lazy and use 40+ then record it and post it on youtube :-)
