This way you will have no problems with bad mana tics. After a bad mana tic you maybe don't have enough mana to cast Thunder 3 after Blizzard 3, but Blizzard 4 costs less mana so you can always cast it (in general you would want to cast Thunder 3 directly after Blizzard 3, so the DoT has a higher uptime, but because of bad mana tics I cast Blizzard 4 before Thunder 3).
When you cast Thunder 3 but have a bad mana tic you will have to wait for your mana before you cast Fire 3, or you will not have full mana when switching into Astral Fire, wich means you will lose out on a Fire 4 or the Despair at the end. Xenoglossy doesn't cost mana, so the mana has enough time to tic to full after the cast of Thunder 3, before you switch into Astral Fire.
