How is that even complex at all? You would still spam the same skills to balance your mana. All you're asking for is buffs. Complexity would mean things added to RDM that doesn't make them a brain dead magic spam machine like mana deduction when using jolt if shatter is available, upgrading the same type of mana thrice in a row, etc

I play both RDM and BLM, and switched to RDM because the mechanics are so punishing for Blacks. Reds manages those with ease and dish out good numbers even without effort. It's so braindead
