Dispensers of fiery explosions, light me up... with your ideas for BLM in 5.0

[Archwizard]

Perhaps a bit of a crazy thought, but...

• Thunder III is Instant Cast.
• Thundercloud removes T3/T4 from the GCD in addition to its current effects.
• All Astral Hearts are consumed upon casting Thunder spells, extending the duration of Astral Fire based on the number of Hearts consumed (2/4/7 sec).
• If it consumes the last of your MP, the damage of Flare increases relative to the time left in Astral Fire when cast.

Then just combine them with some of the previous thoughts...

• Each cast of Fire IV generates one Astral Heart, while Flare generates three if it strikes at least 3 targets during Enochian. Astral Hearts are overwritten by Umbral Hearts. Only 3 Hearts of any type may be held at once.
• While at 3 Astral Hearts, Thunder III is replaced with Burst, an oGCD which restores some MP (equal to the cost of Thunder IV) and consumes the active Thunder DoT on the target/nearby enemies for bonus damage. Sharpcast may be applied to Burst to proc Thundercloud.
• New Trait - Absolute Zero: While at zero MP, your next Ice-elemental spell is free.
• Freeze places you in Umbral Ice 3 if it hits a target, and generates one Umbral Heart per target struck if cast during Enochian.
• Blizzard II evolves into Freeze at level 35, Fire II evolves into Flare at level 50.
• Scathe extends the duration of UI/AF by up to 6 seconds per cast, to a maximum of 13 sec.

Now, if I've done this correctly... in single-target, you would want to use Burst->Thunder III in succession after every third Fire IV, pop TC as it comes up, and end the AF phase with Flare before transitioning.
