Well honestly its the reason I don't play Red Mage much anymore.

Granted Red Mage procs do throw a of Chaos into the job that make it unpredictable...but the reality is, outside of Alliance Raids, Open World Content and Dungeons... you never get to use a lot of the abilities in content like 8 mans. (Healing, Raise, AoEs). I like being able to play the full job's abilities and fully utilize its capabilities. But SE wants to force everyone into 8 man raids where it becomes the most boring thing to play because you only use a tiny portion of the job.

Conversely, I do enjoy playing SMN because it is that intricate and complicated, and in reality "busy" even on Single Target rotations. I STILL prefer content where I am using ALL of the abilities of the job the same way with RDM because SMN has a LOT of AoEs as well... but no matter what the content, SMN's intricacy and wide range of abilities usually come into play at some point (like... 3 different Pets that have 3 different specialties, Single Target, AoE, Damage Mitigation)

Its why I prefer SMN to RDM in High Content. Its way more complicated with a LOT more Buttons and a LOT of multitasking and a Lot more micromanagemant, but it way better than just using 3 buttons every combat.
