RDM Enchanted Moulinet Trois Recast

[TakumiHarada]

Not really, it makes sense. It replaces the filler with a strictly superior version (more damage, more energy, instant cast). There's no use-case for casting Jolt or Impact if you got Grand Impact up, hence it replaces those buttons.

Except when you're trying to flip the dualcast window to not delay the oGCDs. It's been the biggest use of Acceleration since it became a Swiftcast button, and having double instacasts ruined it.
Although Swiftcast's recast got almost halved so it's not as bad.

It didn't ruin it; this is easily worked around by just not Accelerating too early. You're guaranteed at least one proc after Acceleration, so you will always have at least 7s and four weave slots to use Fleche or Contre Sixte while you hold Grand Impact.
