The more I think about BLM changes, the more I find these choices weird and strange.

Flare Star - the more I think about the whole Astral Heart thing, the more it gets weird, cause why it is for the Fire phase? Blizzard 4 gives Umbral Hearts to use in the Fire phase, so it's logical for Astral Hearts to affect the ice phase instead. So Flare Star should've been Ice Age or Absolute Zero and be a very powerful Ice nuke, stronger than anything in Fire phase with AF3 bonuses combined. Instead, there are bigger emphasis on Fire yet again.

Thunderhead - is weird. Flat 200p with a DoT, you get it once when you shift between stances. And with that potency, it feels like using it for anything but reapplying the DoT is a waste. The upfront attack is weaker than the current Thundercloud proc. Even Thundercloud proc had a slight potency loss compared to Fire IV. And new thing is even worse, it lost damage, and you lost the opportunity to use several in a sequence for movement with some Sharpcasts. If they want to leave the whole mechanic as it is, then at least bring up the upfront damage to Thundercloud/Fire IV level (you can use it once per phase anyway, unless you Manafont).

Paradox - just bring the Ice Paradox back. The whole thing about this spell is that it's a dual spell using two opposing powers at once. It was a movement tool + a strong button to press during Ice. I think the 1 GCD of movement is a strong enough reason for this button to exist. They can go further and also make it stronger + count as an Ice spell and recover MP.
