Eh. I dont have BB yet (will level crp to get it as I know it's plenty useful), and atm Ingenuity I works wonders for me. For progress on HQ 2* I just pop Ingen 1 + Rapid Synth(SH2 will be up of course) to the end and it works just fine (though looking back I should prob just RS one time and CS2 from there considering the boost I get from Ingen 1 lol).

I just have WVR and GSM at 50. Dont even use Innovation really. Everything else is 15 with cul at 40. Ive 100% just fine on Vanya Healing/Casting, Rose Gold Circlet, and Rose Gold Ear Cuffs( dat moolah item). More times than not I'll aim for HQ twinthread or nuggets from hasty touch spam(just b/c why not make it easier on yourself?), but If I dont get HQ I still get by fine.

So imho, get the Blessing and use Ingen 1. You'll be gravy. Now if they introduce i80/i90 crafts but dont upgrade our gear? get Ingen II as well. But with the way crafting is going and the new gear that's coming from dungeons/extremes/moogle/CT, and the speed at which prices are dropping......it's not looking real good for us lol.
