Yep! At a very very basic window it's easy to use melee combos when they're up, not worry about optimizing procs, and use Manafication whenever. But then you add in fixing procs before a combo, Swiftcast usage, proactive mana fixing for each Manafication cycle, proper Acceleration usage, identifying when to go with the 110s Manafication cycle or the 120s cycle, and suddenly there's an extremely high skillcap there for RDM.
