Astrologian range tips?

[AutumnsHollow]

Hello fellow healers, I'm a career white mage and I recently leveled astrologian to 60 and I've been playing around with it. It's been a lot of fun and a breath of fresh air but I ran into two problems. Aspected Helios's range, and MP problems.

Toying around with it, I got the MP management problem down, but Aspected Helios's range just always gets to me, I guess I'm spoiled by medica 2's range. How do you guys deal with it's range limitation, and how do you guys make sure everyone gets buffed?

In A1 I can easily hit everyone with medica 2 by sitting directly in the middle ring, but with astrogoian I'll barely hit any melee DPS with it, so I've adjusted myself by "picking" which oppressor group will get my buffs, but I can't help but feel I'm doing it wrong.

I've run into similar problems in other content as well such as void ark, the old towers, certain coil turns, and some trials. Of course I might miss one or two DPS on my white mage with my medica 2, but it was never as pronounced as it is on astrologian. In fights like thordin, and circular areas such as a3, and a4 I never run into this problem at all, so if I could get any tips I'd welcome it. Or to know if this is normal.

I also had one other question, is the nocturnal stance aspected helios shield 130% of the heal? Or is it like succor in the sense that the numbers becomes the shield, for example 345 heal so it would be a 345 shield?
