If you were watching streams during SB, the SB AST opener always involved early Lucid because you wanted to keep it and old COpp’s cooldown timers aligned. So when you extended the AOE opening card, you extended Lucid with it simply so they always lined up. I’m sure AST is different now, but Lucid should typically be used around ~75% MP; and on cooldown for AST specifically since they will have fewer secondary resource for MP management. As far as I’m aware, they’re still the healer that struggles the most with MP if one adheres to ABC.
