1.) You targeted a location with ‘green’ indicator telling you it’s a valid location for teleportation – is it? may be not.
Probably just me not liking how unclear and unreasonable the target-indicator is – if it’s not a reachable location, why is it green then? I was guessing the skill works the same way as how the NPC calculates its traveling route – if the destination is reachable by not jumping and within certain distance then it is a valid location – wrong.
2.) You targeted a location that’s too far for the teleportation, resulting you having to re-active your skill again. It’s very inconvenient when you want to move as far away as possible in an urgent situation – and the skill simply would not work.
It would probably be a way better idea to snap (or constrain) the green indicator WITHIN the range limitation. Because from time to time my cursor would become hard to see on my screen, due to too many visual effects going on on my screen and when I wanted to target a location with my skill, it was impossible to find where my cursor is.
With all those said, if such bugged skills have caused so much inconvenience, there has to be compensation for making mistakes with those (teleportation) skills, or simply, just FIX the darn bugs.
There are also other similar (serious) issues with targeting mechanics in this game that had made the fast-paced combat a rather frustrating experience.
