I know this is a long standing topic, but I read about it and it’s been unchanged for almost a year now, so I decided to add on to the feedback about it.
The way the skill works right now makes the flow of combat completely jagged: kill a pack - refresh a sigil - kill a pack - refresh a sigil…
There are also issues of missing information: we do not know when our sigils will drop, only the last one, so we are forced into blindly refreshing them. Which in turn drains a lot of our mana.
Each cast also requires an animation, since the skill is not instant, which makes playing a class that has no targetless movement skill ever more aggravating.
