You didn't get my point. Succor is 2.5 and NAH is 3s. Everyone is so focused on Diurnal that they tend to forget Nocturnal does exist (I can't blame them), and should be compared to Succor as well.
At the moment it's either a 5% faster Medica II with Succor's range or a 5% more potent Succor with Medica II's cast time. That's my point.
