I've been trying to finish Titan Hard Primal Battle for like 5 days straight, from shouts to Duty Finder. Every time I get in my party Fails. Now it always seems like its Lag when we fail. I by no means am a excellent dodger for Titan's AoE moves, but I can dodge just about 95% of them. Dealing with Ifrit and Garuda Hard Primal Battles weren't really all too bad. And maybe I'm just imagining it but seems to me Titan does way too much Damage and too many AoEs in a row. Sometimes giving Healers not much time to heal anyone. (speaking about points past Heart Phase)
I don't know, just totally fed up on it. I'm probably on my 0/34 no win streak (That's a never have won battle yet kinda thing.) I highly suggest people read and give their experience for this fight and possibly could get this looked into. Its just way too hard.
