Treat Wrath and Starfire as a pair
The demo version of Eclipse links Wrath casts to faster subsequent Starfires. Read the talent and track its charges: repeatedly casting only Starfire would ignore that interaction. An optimal sequence still depends on final tuning, equipment and combat logs.
Plan your mana before your burst
Improved Wrath and Moonglow affect mana spending. In a long encounter, that can change how long you continue dealing damage without a break. Moonfire and Insect Swarm are periodic-damage options worth testing; a short-lived target may die before the mana spent on them pays off.
Moonkin is a group decision too
The demo tooltip says Moonkin Form’s party critical bonus does not stack with Leader of the Pack. Healing spells cannot be cast in the form. If emergency healing is needed, anticipate leaving the form rather than treating Moonkin purely as a damage button.
