Tbh what you explained would fit well for bluemage, bluemage is overpowered and has crazy good and strong abilities that is why it can clear mechanics with its skillset. Normal jobs cant because all jobskills in this game are tuned to be "weak", just exist to chip off boss HP % a bit at a time. I miss those smart plays too, those we know from other games. Maybe you can find something in deep dungeons or eureka/bozja, where you turn a bad situation into a good one, because you have good niche skills to pick from for the situation. But SE is afraid to bring those skills into the main game - they are kept for "fun side content".
