Guild Wars 2

This renown heart appears to expect you to help the skritt in this cave system, but as soon as you get in range of most of them, they start attacking you. Only the chief and the heart vendor appear to remain friendly. From reading the text, you are supposed to protect them, spar with them, fix flags, etc. to progress the heart, but instead you have to kill them before they kill you, which also appears to progress the heart. This seems broken to me. Either fix the skritt or the heart text.

Bugged.
