BLM Mana tick, Solution and New Rotation

[Louro999]

The best one that works for me is to just keep my eye on mana ticks and wait extra 0.5 seconds or so accordingly. Your UI3 buff just disappears 0.5 seconds earlier than before and your AF3 applies at the same time as always, and nothing about mana tick timings has been changed as far as I know.

That is exactly what I am doing for classic rotation, but this is a DPS loss and when you just used a Thundercloud proc right before your Blizzard 3 (= you don't need to cast any Thunder after that blizzard), you cannot simply go back to F3 ignoring thunder because you will now have 0 MP tick, whereas you used to get 2/3 of your MP back by doing this. Ignoring thunder was also very good for Trash Mobs with low hp. Can be replaced with Scathe but far less effective than going back to F3 right after B3.

Someone explain me how this can be logical:

Buff Umbral Ice 3: Cast Fire 3. UI3 is removed 0.5sec before the end of the cast.
Buff Umbral Ice 1: Cast Fire 1. UI1 is only removed when your spell hits the target.
Buff Umbral Ice 1: Cast Fire 3. UI1 is only removed when your spell hits the target.

Someone explain me how this can be logical:

Because only at 3 stacks do you get a reduced cast time. If you want to try to game your mana regen with lesser UI stacks, you can (like for double Flare).
The cast time will still make it a dps loss and it will be unreliable.

So really, they only needed to change UI3 since it has that additional effect.

Because only at 3 stacks do you get a reduced cast time.

And so what ?
How the cast being faster could justify that the buff should be removed before the spell hits the target ?
UI3 is removed 0.5sec before the end of the cast wheras UI1 is removed after the splell hits the target.

Absurd.
