It appears that Hastega and the Ifrit, Shiva and Ramuh wards are receiving two buffs to duration. One is with relation to summoning magic skill and then an increase to the base duration as well. Hastega could already reach 5 minutes. I wonder what the new cap will be.
Avatar's favor has also been buffed. I guess we will have to do some testing to figure out how the effects increase with skill.
