GentlemanLoser, that's just a free win to any mace of disruption user, no?
How would the absence of this new amulet change that? ;)
Well if you have a 4 man team, and have 1 equipped with it, then you get the AS of a 3 man team.
Then it's useless and offers no benefit.
You want it to neuter Decay, by giving you a 20HP meatshield on an AS backed multi minion team. But it would take the AoI slot, which would mean this 20HP minion is killed by a MoD (because of PL) in one swing, and then Decay does its stuff anyway.
Now, if it wasn't an amulet, we just might as well make multi minion teams immune to Decay.
But I'd let this item go, the moment we get another Leadership item that would allow me to reach a 100% damage Decay! ;)
