About Horn of Gandarr animation time

Is it just me or does this skill’s animation seem painfully long? I’m trying to incorporate it in some of my non-elemental inquisitor builds for damage reduction, but it just feels so bad to use, especially for a default attack build. Am I just imagining this or is the skill animation really that long and clunky? Has anyone measured it? Could this be fixed somehow?

Casting speed?

No, it’s rly slow, also with high cast speed. You cannot machine-gun HoG with rimetongue, it remains a bit clunky.
