I tested deflier set, since it should be inbteresting to be used if vet dungeons for stam builds due to the ability to the hunger to hit several ennemies. Also tested it in pvp and duels just to see if it is efficient.
After several tests on mobs, skeleton and other players, I can say that it could be usefull if the hitbox of the hunger wouldn't have been broken.
Indeed : even if there is a red cone in front of him (when you are the victim), the hunger only touch ennemies if he is ON them (instead of being in front of them). So basically, even if the set explains that he can hit all ennemies, I rarely hit more than one ennemy.
Also, often, the hunger die doing nothing when ennemies are too far -_-'
That should be fixed, because even on skeleton, which is not moving, the set works less than half of the time.

That's my impressions, feel free to leave a comment about your own tests !
