This right here. This whole conversation about Relius pros and cons was actually a pretty good read.
My problem with Relius is that if I managed to get through someone's defenses or start pressure, Ignis is already about to break. This leaves me having to cut some combos short or bailing right out of my own pressure. In CP they made this problem even worse by having Ignis meter decrease faster while idle. Relius piss poor mixup doesn't help things either.
He may have really good damage, but he has a whole laundry list of flaws that Uri just listed. It would be lovely if Ignis was as resilient as Ada.
