My own wishlist:
- Consolidate Ley Lines and Between the Lines, Fire 4 and Blizzard 4, and possibly Flare and Despair and Foul and Xenoglossy (through simple potency and animation alterations when one would strike only a single vulnerable target with either).
- Remove the Enochian requirement from Fire 4 and Blizzard 4. Instead, Enochian becomes a burst/utility CD.
- Make AF/UI stacks more intuitive. Remove the 5/10/15% cross-element penalty, and just have each stack give 20/40/60% less MP cost and less cast time when casting the opposite element instead of 50/50/75 and 0/0/50% respectively. AF gives +20/40/60% extra damage. Fire potencies are increased to match, but Ice potencies are also increased up to the potencies of their paired attacks (B1 base potency = F1 base potency; B2=F2; B3=F3, B4=F4, Freeze=Flare, etc.) UI increases the MP given per stack by 20/40/60%. Base tick increased to match. At 60%, the first marginal tick is enough to give access to B4, but not T3, as in SB. Being in AF at all still doubles Fire costs. Being in UI at all doubles MP generation. THM will also have uniquely high MP generation to begin with.
- During UI, using Fire spells which grant fewer stacks of AF than you currently have of UI will simply remove that many stacks of UI rather than both removing all beneficial stacks and giving you nothing in turn (as they do currently). When it gives stacks AF of equal to or greater than your UI stacks, it simply switches you directly to those stacks (as Fire III/Blizzard III alone do).
- Transpose has a 12-second cooldown again, but 2 charges. This gives more deliberate use but also opens up some new options.
- Scathe removed. You now already have plenty of quick-casting options via aspected spells.
- Flare potency buffed but again has significant taper. Freeze still will not, despite having equal base potency, since it does effectively 60% less potency anyways.
- Fire II buffed not to be worthless. Blizzard II now on-target. Generates a stack of UH per cast later. Freeze changed into a long-cast, situational nuke, pausing MP generation over the cast (do not progress towards next tick) to cast a massive high-potency stun that generates 3 stacks of UH. (Think Shiva.)
- Instead of dealing with clunkiness all the way to level 72, allow MP to progress towards its next tick even while in Astral Fire, ensuring the first tick in UI is instant. Halve the effect of each tick, but have each tick at half a GCD's time, keeping it rotationally consistent over varying Attack Speeds and more smoothly granular in its pacing. This means there's still benefit for maintaining an MP margin beyond merely having just enough for a Blizzard III.
- Revise Firestarter. Spread out its RNG. Have the relative potency (Det, Crit, and DHit-affected, but not affected by main stat) of all Fire casts build resource which can then be spent on any normal Fire spell (i.e. any but Fire IV) to quick-cast and free-cast it. Fire IV only generates half as much of this resource as the other fire spells.
- Fire spell animations now scale with stack count.
- Remove Aspect Mastery. Flare/Despair should in most cases remain a deliberate, but competitive choice, rather than just a rotational finisher.
- Enochian then fills the rotation-adjustment niche left formerly by Aspect Mastery, as a burst CD.
- Enochian originally allows you to hold both UI and AF at the same time, thereby extending the period over which you have reduced MP costs (similar to Umbral Hearts) and quicker casts, while increasing all stack bonuses to 25% each. Thus, during AF, UI stacks are shown but muted to show that they are not generating MP, only continuing to reduce MP and cast costs of Fire spells.
- At level 72, Enochian is upgraded to also allows the generation of Astral Hearts from Flare/Despair (3 at a time) and Fire IV (1 at a time), which allows your next cast to act as if affected by three further stacks of Astral Fire, meaning 0 MP cost on Blizzard III after Flare or up to a 250% damage Fire III (yes, the animation affected). [Archwizard's idea, stolen and altered only insofar as I feel it's only necessary as a way to give a rotation similar to that of Aspect Mastery as a means of burst, via Enochian in this case, rather than as something to be used constantly.]
