Shard of Endless Avalanche is bugged in at least three different ways.
1. Sometimes Shard doesn't even spawn. This will happen on flat terrain as well as curved (cave bridges etc) terrain. The skill also goes on cooldown, so you've effectively wasted cast time, and wasted an encounter slot.
2. Will occasionally fade out mid roll, rather than explode or sit. I don't know how to reproduce this one either, but it might happen during some kind of pathing calculations.
3. The cooldown is improperly listed. Mine for example says 14.9 sec CD. It has said this since rank 1. Even at rank 3, it still takes 14.9 sec to CD. Whats even worse is it actually takes 20 seconds (if you cast it and see the countdown before it gives you the first opportunity to push it)
All of this happens whether in tab slot or otherwise.
