Have I been living under a rock? So i'm a lvl 50 wvr and 15-30 in most everything else.......EXCEPT CULINARY!

So I keep hearing about this hasty touch so I look it up and its 100% efficiency 50% success rate. Costs zero CP. I'm assuming of course it costs 10 durability unless you're using Wastnot.

So is that the best way to increase Quality? Generally I use the the 42CP Quality skill with SH1 and Great Strides?

Pretty much fully geared BiS other than materia. Haven't tried a 2star yet. Is hasty touch the ONLY way to go or??
