Guild Wars 2

Shadowstep, based on gw2 wiki:

It allows the player to move vertically as long the position can be reached normally by moving on the ground without jumping. Trying to shadowstep up or through obstacles or across gaps will cause you to shadowstep to the edge in general.

However, this ability seems to behave inconsistently on stairways. Please refer to the attachment. These pictures are taken from World vs World’s garrison.

There is a visible visual difference between these two stairs on the picture, with the latter (jagged stair) could be regarded as obstacle when this skill is trying to calculate the path.

Is this expected?

Thanks!

Similarly, Mesmer’s blink does not work on most stairs in WvW. It just teleports you in place. Been like this for as long as I can remember.
