Some personal changes I'd suggest:

Fire IV and Blizzard IV potency changes from 260 -> 280-300 (Reasoning: Further damage is necessary for BLM to maintain its position as a good turret DPS without making it absolutely terrible as a result. Make moving less punishing.)

Foul Potency changes from 650 -> 700 (See above)

Scathe Potency changes from 100 -> 150-200. (Make this a viable, emergency mobility attack)

Enhanced Scathe Effect changes to "current duration of Astral Fire/Umbral Ice increases by 3s to a maximum of 13s." (Keeps Enochian while forced to move)

Manaward: Decrease cooldown from 120s to 60s (because we're the turret class, and beyond Scathe being a movement mitigation, this is a damage mitigation to accentuate turreting without being TOO durable).
