For example, you just used Gust Slash and it's 1000ms before the next GCD is ready and you're behind the boss. The profile will use Aeolian Edge because that's the highest potency skill you can use at that position. At about 500ms before the GCD is ready, the profile will tell the game client to use Aeolian Edge. At about 400ms, you suddenly change to Flank position. The profile will still use Aeolian Edge and you will lose potency. Without skill queue enabled, the profile would have used Armor Crush (flank) for higher potency even with the sudden changes in position.

Ahh, thank you for your response!
Makes so much more sense why skill queuing is used in your DRG profile now ^^
