Hammerjaw is one of 2 arcane pets that are so desired to have.

Being arcane and incredibly expensive pet, it doesn't provide any amazing bonuses and have poor damage (not on stat page). I tested it on mobs in elite and in daily token quests - malison that has multi-target attack kills faster single target than hammerjaw with its 136dmg. When there are a lot of mobs - malison is even more better. Testing party buff it not resulting in faster elite farms.
It's party spell is comparable with deary, how can it be fair? When next cap comes glacian and hammerjaw +10/+15 to stats buffs will be nothing special.

Is it intended to be just cute sharky used as decoration? Why malison is so much better?
