What's the big deal with coa? I dunno what the big deal is about coa. I have a few, including one really nice one. I traded even nicer ones for sojs and high runes (east ladder). But when I look at, it's not that great unless you use those 2 sockets really skillfully, but honestly, most people I've seen use just put 2 ums in there. The thing I don't get is, kiras guardian provides most of the benefits as coa and pdr can usually be reached with ss/verdungos anyway. What are you guys using coa for? I have 3 on mules I want to deal off since I think it's fairly useless.
