Guild Wars 2

After a long stint of ignoring my tempest I decided to take him up again. I played it for the better part of the day yesterday and really enjoyed it, which was a nice surprise. I was Dagger/Warhorn. I was wanting to know a good rotation for buffing my teammates during the 10 second pre-match countdown. This is what I was doing, please tell me what you guys would recommend.

Fire Attunement
-Overload Fire
-Heat Sync

Air Attunement
-Cyclone

Earth Attunement
-Sand Squall

after this rotation I would go back to Air Attunement to get Overload Air ready for combat.

optimal rotation:
apply swiftness at 1 second left

In my experience, unless you have a rev with the boon duration facet up and you are using runes of leadership or something, your boons will wear off before you engage the enemy

Personally I use d/f build and start with:

Air Attunement:
Overload Air (At 7th second of the counter, another 2 skills right after)

Water Attunement:
Frozen Burst

Earth Attunement:
Magnetic Wave for team swiftness
