Only 1 secondary, and significantly less value than the VP bracers. Curious if the stat budget is random, or if everyone is getting wacky stats like this. May not be able to find something better itemized than Bracers of Mutagenic Fervor in heroic.
So you could through in some stat weights here and play around to see which is better. But I can tell you right away that they are going to be very close.
Look at my bracers in my armory in my sig (click the banner). I was lucky enough to get Thunderforged version . Anyways... at first, I thought these bracers were crap, but then realized two things... 1. They have a socket with a decent bonus... 2. The lone secondary stat, luckily crit in my case, is almost double the amount of crit my previous bracers had. I had the 2/2 version of the heroic bracers from Stone Guard.
Yeah, we saw some tank bracers with ~900 parry on them. Highly possible then that those random enchant bracers are actually designed that way, to have only 1 secondary stat. Looks like with the slightly extra agility you get on the Beady-eye's, that they should be pretty comparable.
