I’d like to add to this, the actual item level of that item is not 457, but more in the range of between 482-486, thus being the strongest weapon in the game by 32-36 item levels.
I’d also like to bring some attention to this thread Done with this legendary system made a few weeks ago. A guy at 3.5k rating in M+, needing this to push further and tired to seeing casuals gathering herbs and having that weapon dropped from LFR.
This system was a mistake, one which I hope Blizzard will learn from with the new upcoming one. This item should have a low % to drop on LFR, but maybe like 20% from Normal, 50% from Hero and guaranteed for Mythic. Right now even in Mythic it’s hell to get it. And despite the %, there should be a huge bad luck protection, say if you kill him 5 times with no drops the 6th is guaranteed or something.
Or drop the power altogether so that it’s not mandatory to have for higher tier players. Like maybe a 2-5% power increase compared to Mythic end-of-raid Weapons, so that for very high tier players it isn’t that insane but it’s very big for more casuals. Right now it’s so powerful that it will be most likely equipped on Mythic Players of next tier, despite the Mythic Ilvl going up +39 instead of +26 like usuals.
