The reason that happens is F2’s 3.0s cast time and huge MP cost.
My Fire 2 would be 144 per target per 2.5s. Flare is 292.5 on one target and 175.5 on the rest per 2.5 seconds, so it’s still flatly superior to F2. A “hot Freeze” is 70, and a 2.5s Freeze is 100.
So, you’re level 50, just swapped to AF3 and have 9500 MP and three targets. You can cast five F2s, then Flare. That’s 1.8[240*5 + (260 + 156 + 156)] = 3189.6 over 16.5 seconds. Then you cast hypothetical always 0 mp Freeze (210 total potency, 2.5s), B2 (filler to regen MP, no lag before the cast since it’s free in UI3) for 240/2.5s, T2 (more filler to get your MP up and keep the dot ticking, minimum 450 potency/2.5s), now your MP is full so you can cast F3 for 168/2.5s and GOTO START.
That’s 3189.6 + 210 + 240 + 450 + 168 = 4257.6 potency over 26.5 seconds -> 160.6 pps.
Forget F2! We’re just going to cast Flare, then hypothetical 0 mp Freeze, then B2, then T2, then F3! So 1096/4s followed by the 210+240+300+168 over 10s. 2014 total Potency over 14s becomes 143.8 pps, not as good, and the more targets there are the better relative to Flare non-Flares become.
Okay, what if we didn’t even bother with the B2 filler or even T2 and instead just mashed the F3 key, waiting for our first mana tick? Well that’s an average 1.5s lag time,
so 1096/4s + 210/2.5s + 168/~4s. 140.38 average.
I think I may have cracked it - this is a sensible sub-68 AoE rotation!
Aspect Mastery is written misleadingly but behaves in a consistent way. It reduces the MP requires to cast spells of the opposite aspect to zero. However, it doesn’t change those spells’ EFFECTS. Flare is best understood as a spell that COSTS 400mp (doubled to 800 under AF3) but, in addition to dealing damage to enemies, burns away all your MP (or just burns away a portion of your MP if you have any Hearts) on-hit.
- There's already an AoE that gives you AF3. Aspect Mastery reads without ambiguity, and I quote, "Accumulating full stacks of either Astral Fire or Umbral Ice then casting a spell of the opposite element will consume no MP" -- yet Flare is the one unmentioned exception to this, whether or not you have Umbral Hearts. You want a match made in heaven, fix that interaction and marry those two, because you're going to have a very hard time convincing me that the new trait is meant to ignore it in the same expansion that specifically changed Freeze to make Flare usage smoother.
- "If Fire 2 simply didn't exist at all" is quite amusing justification in this case, considering you're attempting to retool it into a completely different ability -- Fire 2 as you wish it to be doesn't exist. You're tuning more than just the potency, but the overall cast rate and its impact on the rotation, creating a new tool with an old name, used in a completely different way from its namesake.
Even the existence of what we have (as with Blizzard 2) has been considered an "oversight" from level 50 on. But again, this is literally why I stated that they should simply upgrade to Flare and Freeze, as your behavior with regards to AoE is rather permanently affected either way.- I find it quite curious that you advocate creating more parallels in the positions of our Fire and Ice spells, yet also want Fire 2 to carve out a spot as the parallel to Freeze for the purpose of swapping phases in AoE. You also haven't really covered how you intend to rescue its actual counterpart B2 from its status as a bloat skill.
Because, and I can't seem to stress this enough, that's what Fire 2 and Blizzard 2 are: bloat skills. Ones you're attempting to justify as more than that for niche purposes, but bloat all the same.
I also don’t actually want Flare to be your free-to-cast AF3 swapper; it’d make the AoE rotation feel more samey and leach some of Flare’s identity as a devastating but costly finishing move. No more cold flares!
As I’ve mentioned, you can’t have F2 simply upgrade into Flare because Flare isn’t strictly better - it casts more slowly and eats more MP.
4.0s Freeze would prevent it from being spammed to the exclusion of fire spells at lower levels and also mean that a hypothetical UI3-granting B2, rather than Freeze, could be used to rapidly recover UI3 and hence all your mana post-death or stance fumble.And what was your justification for nerfing the cast time of Freeze in the first place, again? "Making Freeze spam less attractive than Fire 2" wasn't it, which is only a problem while leveling?
Then we end up with the humorous possibility of Flare returning to its original form, meaning saving Swiftcast for Flare in single-target to burn out the last of our MP as a prototype of Despair -- before we even have Aspect Mastery -- and then using Freeze in place of Blizzard 3. If the numbers happen to support that possibility now then it'll cascade to Flare and Freeze being nerfed in prevention.
