This is the best pvp weapon for a warrior at this point in my opinion. the mace-specc is extremely useful (especially in 2on2 and 3on3 arena). Though it has no extra stun-proc (like stormherald)the extra damage and stats fully compensate this. The look of this weapon is also great, the top of the weapon rotates around the glowing core ... sweet. If you don't like this weapon(because of the look)or play only 5on5 i suggest you go for the sword.
hf and gz to everybody who owns one of those
