As the title says, the six rune fear effect very rarely triggers. Against lower level enemies in an open world zone it does trigger, maybe perhaps 3% of the time. Against dungeon trash it triggers rarely, at most once in a dozen dungeon runs maybe. Against any sort of veteran it never ever triggers which seems fine until you realise that a lot of trash-like mobs in dungeons/fractals are actually veteran.
In effect, the six piece bonus seems to never trigger in any dangerous situation and to be honest it seems as annoying as beneficial on the rare occasions it happens against trivial mobs. I don’t know what level scaling and resistances are involved but can this be please be reviewed so that the six piece set bonus for this dungeon armor is more than a fanciful oddity?
