Guild Wars 2

I’ve been playing a hammer warrior for a couple of weeks now and have noticed some annoying mechanics. It mostly has to do with terrain. I’ve noticed that hammer 3 and 4 will miss if a player is above or below you on a hill. The f1 burst will also miss if you try to use the skill from a higher altitude than an opponent (similar to sword 2). It seems the attacks just take a straight path from your character’s position instead of following the terrain. Is this intended or something that will be fixed?
One other question that I have is about the shield 5 ability. The description says that it blocks all attacks for 3 seconds, yet pulls such as a thief scorpion wire will end the ability and pull you towards the thief. Are pulls such as scorpion wire not considered an attack?

I dont think they are considered to be attack. You cant block the mesmer pull/push thingy either.
