The ability has been called different things throughout the series (Doublecast, X-Magic), but I think something like this would really help RDM out. An ability on a 2 minute or less cooldown that makes our next spell cast on the target twice. This would obviously only be useful for nukes and cures, but I think it could give RDM some sort of "burst" that might bump them back up towards where the other jobs are at. Plus the cooldown would keep it from being overpowered.

Opinions, ideas? Would Tricast be too much? What about MP cost?
