Guild Wars 2

This has been a problem for many of Necromancer’s skills.

I have not found all such, but I do know that

All Lich Form skills goes on full Recharge when interrupted, instead of the normal few seconds Recharge. This means that if e.g. the Jagged Horror mark skill#4 is interrupted, you cannot cast that mark at all, thus wasting the entire Elite skill of 180s Recharge.

Lich Form skill 4 (Jagged Horror mark) still goes on full CD if interrupted, making you unable to use the skill at all as you time out before it is off CD again.
I’m not 100% sure of the other Lich Form skills, but I am 100% sure that the skill4 is bugged.
I don’t see this issue in the bug tracker with the 23 March update.
