Black Mage Blizzard II (and other minor suggestions)

[KayliRose]

Maybe if we were playing in a game without excessively high-enmity tanks, our positioning would matter enough to differentiate between Ranged and Melee that way, but honestly it just comes down to Melee having their first pick of spots for spread AoE / tower positions while priority thereafter goes to whoever has the least mobility.

With tanks being so powerful and CC so lacking, there's no point at which you're going to lean on a Ranged's range "advantage" outside of soloing, and then only as convenient. In this game, XIV positioning near or far from mobs means almost nothing without simultaneously necessary arena positioning.

The benefit of being at a distance is to be away from melee range AoE's that would otherwise be a burden on casters who would need to move to stop casting. The enmity means nothing if you're close enough to take an AoE to the face. At which point, the argument I've been making all along should be clear: If you're close enough to use B2, you're close enough to be interrupted by close-range AoE's.
It's just common sense, which would you rather do, avoid the risk of interrupts for close-range attacks, or just stay at a distance where your only risks are the targeted AoEs that you can THEN focus your energy moving away from? There's literally no need to use B2 when you have more powerful spells that have less risk, even at low levels. Most monster groups at the levels where you would use B2 don't have targeted AoEs, and few bosses have them at all up until Haukke Manor or Brayflox. So why not just stay distanced so that you can move around less? BLM's whole shtick is by being a caster with significantly long cast times, they need to stay stationary as much as possible. Why burden yourself by needing to move every so often from a melee range cast or just to get in close enough to cast such a spell when it's just plain easier to cast from a distance?
