Amendment to that: FoF lasts for 30sec. If you pop it before 1st goring, your last gcd before FoF expire is ra. FoF > GB > RA combo > RA combo > GB combo > RA combo > FoF ends. In a lot of the cases using FoF right before goring blade can be undesired, you potentially apply less FoFs throughout fights, sometimes you aren't using the full uptime like if boss dies/jumps and you have like 10secs left on FoF etc. In some fights, activating FoF at pull is a gain dps, for example a6s where you pick mine as pld or nidhogg where he just flies very quickly. It's always fight to fight and phase by phase basis.

So long as you have 2 gorings in each FoF you can consider it under the ideal circumstance, the bonus being ra buffed instead of roh which falls under that small nitpicking that nets you more potency.
