So I'm 64 now and some things I noticed. You can really feel that you don't have Sustain any more. When running FATEs I just used Garuda and had Chocobo heal me since I was tanking. Titan Egi is very limited now in use to the point he can't even survive the class quest. We really really need Sustain back SE.

Ruin Mastery seems to proc often enough

Devotion doesn't effect you, just the one random party member lucky enough to be near the Egi so yea, I feel it needs a change to something like all members in 15 yalm radius.
