While I'm not a good shield healer, for all I've tried recently, I can't help but hate Eukrasia. I wouldn't have a problem with it if it were an oGCD but in my experience my entire flow just stops dead whenever I have to press it, rather than Dosis, Dosis, Dosis, Eukrasia, Something; It feels like Dosis, Dosis, Dosis, pause, Eukrasia, Something. There's nothing stopping them making it an oGCD.
