Guild Wars 2

Whats the actual criteria for this Achievement ? i must have done over 50 walls/gates and im still on 10/15 ? is it bugged or something else ?

You now that you have to use siege to get those or at least some of your party member have to use siege.

Actually use the seige or just supply it ?

Use siege.

Ok thanx , but i sometimes get it for just hitting the doors , maybe i must have been in a group that used siege ?

I got some of mine from just hitting it. You just have to do enough damage to it.

Earlier thread with reply from Devon stating how its done, you dont need siege, you just need to do a certain amount of damage to the gate

There is no way in hades you can do enough damage to a gate on your own, to take enough credit for the break when someone else is using a ram right alongside you.

Your best option is to find a nice safe tower, build a treb and start pounding a neighbouring tower to rubble.
If you can do that in such a way that it helps your side in the battle – so much the better.

PS. Overlook vs SM or Anza is easiest – that’s why there are suddenly dozens of trebs lined up along that lower wall.

Pvdoor in group of 5 often gets credit. Depends on how many rams and if in Zerg of course. In group of 10 ish though it works….
