AST Astrodyne Harmony of Body Effect: What does it actually do?

[Rein_eon_Osborne]

Macrocosmos is a spell but Harmony of Body Effect doesn't work... What a scam

If you read up to the last sentence of the tooltip, it tells you that the action does not share recast timer with any other actions. You can guarantee any other actions that has this description will not be affected by this sort of 'Haste' buff. They could've used a better wording, but it's not a scam.
