Guild Wars 2

I (Ranger) have an issue with graveling burrows. When I come as meele most of my attacks miss the burrows, and when i use ranged weapon i get the “obstructed” message.

Is it only me or anyone else has that problem?
I play on Piken Square

Everyone I know who melees those things has the same problem, I even tested it one night and sure enough couldn’t hit it unless standing in a very specific spot.

I figured that out too and from my point of view it’s some bug, cause if you have to stay in specific point, you can’t dodge or run away from mobs, which destroys the game mechanic
