I dont play the job so I cant really answer this question. But a friend o mine hit 50 on ninjas recently and when doing big pulls in dungeons I suggest using the aoe attack that has them through a buncha daggers on the ground (cause thats what ALL ninjas do) bu he insists that Doton (or whatever the fire ninjitsu is) is AOE, does more damage and doesnt eat up all his tp like the dagger aoe does.
So what do you guys say? I mean i would think the dagger aoe is clearly the right one since thats the one everyone else uses.. Is doton really better?
