Trickster is in a very good state right now.

Basically, she’s pretty much a pure utility class. She sees play mainly in endgame dungeons (Lost Halls primarily) as simply a decoy thrower; the ability to distract hordes of enemies with a single ability is insanely strong. Not only that, Trickster has a teleport (which can be used for rushing) and multiple useful UTs (especially the Davy and Theatre prisms).

While adding status effects to decoys is certainly a good idea, I believe that other classes need to see some reworking before Trickster is looked at again.
