1. Titan is not overtuned. The DPS requirements aren't exactly high as other people think it is. They just want to move phases exactly like the guide video so anything out of the ordinary makes people freak out and forget common sense.
2. I sincerely enjoy Titan the most out of all the primal fights. It's one of those fights that if you learn it well, you can do a lot of difference compared to when you didn't know better. It even has a set rotation so you would know exactly what would happen before it even comes up on the screen.
