Restoring Breath is all the way at lvl90 though.
As for quicker, Metallic Body + Spirit Link is still affected by the recast, but you might be willing to use it more often. /RDM's Stoneskin is a bit stronger, though it comes at a later level.
/RDM does get a few nice spells later on, but BLU keeps things simple - you won't be caught up casting as much, but you also won't have Dia/Bio, spikes, en-, etc running.
