Mnk can also aoe pretty effortlessly with cataclysm
Meh, you can simply Spinning Attack (use Godhands) those days. Depends on buffs it can even one shot trash, but usually 2-3 shot depends on MA proc and if you target Transcendent mobs you will kill them too at the same pace with additional damage from melee and fusion skillchain.

Still Blu is simply way better, because it's faster to execute and requires 0 buffs. It's also easier to gather mobs with all the defensive spells and you dont need to deal with positioning or engaging. 1-2 spells and all trash is dead. Also Expiacion> Savage, Tenebral is better than armor break, because it doesn't require TP and you can cast it during TP move (when you would need to stop physical damage anyway) on Kin and do magical damage while applying def down. It also means you will apply it every time Kin will erase it with Sphere.
All that being said, it's SAM thread and "go different job" advice has sense in something like Sortie thread, not here. If someone want to do this on SAM its by choice, not requirement.
