Guild Wars 2

So as far as I know, skills such as blink (http://wiki.guildwars2.com/wiki/Blink), Judge’s Intervention (http://wiki.guildwars2.com/wiki/Judge%27s_Intervention) and merciful intervention (http://wiki.guildwars2.com/wiki/Merciful_Intervention) use the teleport mechanic, which is different to the shadow step mechanic, in that with teleport you can get to places that you wouldn’t be able to walk to in a straight line, or would need to jump to get there (or you can get to ledges which would normally require you to walk around).

Sometimes this works for me, I am able to teleport to enemies on ledges, or on different platforms. But most of the time in these scenarios the skill fails to teleport me to the enemy player, even if it’s accessible by walking (such as a bridge).

In the beta when I was using blink as a mesmer, I was unable to blink to places such as large tree stump, or a stone wall. Sometimes this worked, sometimes it doesn’t.

The wiki says "Unlike teleportation, you can only shadowstep to areas normally accessible in a straight line without jumping. Trying to shadowstep up or through obstacles or across gaps will cause you to shadowstep to the edge. " so either the mechanic is bugged, or the description is wrong, and shadowstep and teleport use the same mechanic.
