For AOE, you may think this is insane but you can cast Verthunder II -> Veraero II -> Impact to reach 10 Black and White Mana using 1 hardcast Verthunder II, 1 dualcast Veraero II, and 1 acceleration/swift cast Impact at level 90. After your last Veraero II, you can enter Manafication + Embolden -> Go into Moullinet Combo. Plus, it aligns with burst phase on the 3rd GCD. After the initial AoE, you should never be running into the issue of not having enough black and white mana for AoE when using manafication due to the initial Verholy/Verflare + Scorch + Resolution generating black and white mana as well. This is generally the worst case scenario though.

Personally, I never have an issue with not having black and white mana in AoE as I start casting as the tank is pulling, dual cast & immediately gap close with Corps-a-corps, acceleration -> Impact for a new weave slot, then use displacement to pull myself ahead of the tank and to continue casting + dualcasting. I generally am way above +10 black and white mana when the tank stabilizes their pulls, so I never really need to waste time trying to gain the extra 10 black and white mana before entering embolden + Manafication burst phase.


For RDM's alignment, I think the goal of RDM optimization is exactly to know when to utilize Acceleration and Swiftcast to reset your alignment properly, as well as utilizing them for extra weave windows. Having your single target melee combo activate at 50 black and white mana rather than at 80 also encourages utilizing your melee combo to help create windows for utilizing your Fleche/Contre Sixte skills. I don't think their quick spells need to be 1.5 seconds for that reason.

The only time drifting becomes a huge issue in the rotation is when RDM needs to verraise, but that's basically the utility raise tax RDM pays for saving the run.
