Make it apply blind to anyone who gets burned, once per target (current 8 secs ICD). It makes no sense that it only applies to the first target your burn (like a mesmer clone, or a pet, or minion), and that the ICD starts there, when a non-grandmaster trait for mesmers does essentially the same thing for each shatter, with no ICD. It would give eles a reason to go away from water/arcane as much, and would give us some survavility outside of healing. Together with the fire trait that takes conditions away with each aura applied, this would buff tempest, which IMO, needed it. A new water/fire/tempest build could come up.
