It's usable, sure. I wouldn't say it's garbage, but I think it's self use. To hit 102 fcr BP you need 17+ with 2 claws. That being said, I like going one frame before (65) cuz it's easier and more gear options.
Even going for 65 with this ammy, you'd need at least 10 fcr to save a ring slot, so it's pretty sub optimal. Coupled with the fact it's not a +2 all, I'm not sure you'll be able to sell it. Just my opinion.
I think this because martial arts these days = mosaic. If you run mosaic, you run 2 claws (0 fcr) arach (20) Griff (25) then you get into options. Fcr rings vs soj/bk, fcr ammy vs mara, fcr gloves vs 2/20, etc. so basic set up you're looking at 45 fcr.
