I've had all of my GF's (Up to Ifrit) learn 'Boost', but there is no option for it when summoning the GF. On the PS, there was a small button that would appear allowing me to boost the power of the GF, but it does not appear here. I've been to the Config program and remapped the 'GF Boost' to 'V'. but that didn't work either. Any other ideas?
