The level of these have been changed for launch. Each Hand class gets a cross-class ability @ 15, a 2nd @ 37 and a 3rd @ 50. The 15 & 50 ones are linked thematically usually, sometimes the 50 is a "II" version of the 15 one. Most of the 37 ones (GSM & CUL aside) are effectively double-progress abilities AS LONG AS you are using that element's shard/crystal/cluster. E.g. CRP gets Brand of Wind @ 37. If you use this on a craft that uses Wind crystals, you get double your normal progress.
WVR is probably the best one to take to 15 straight away. The ability is a
guaranteed progress (100% hit chance)
(here is the link) - great for ekeing out that last bit of durability from the craft. Also, you can craft the lower-level crafting gear to get you started on your other crafts, plus gathering gear as well.
