I still think it should be 1 second, and 1 second... Flows better ya know... I suppose the guy that wrote it is dead, so I can't write him a letter huh

Anyway, COA is not a good choice for most WW sins, however, there is 1 case where it would be a decent choice. If for some reason you couldn't get your hands on some duped boots to upgrade into good kick boots with lower requirements, you could always use shadow dancers. This would mean you have to pump str way up to wear em, and it would cost you somewhere around 400 overall life. There are benifits however, since shadow dancers are amazing boots for kick damage. They have 2 shadow skills for extra venom, 25 dex so you can save points on dex, and lots of fast hit recovery. If your wearing shadow dancers, you would then have nearly enough str to wear COA. A few more points in str and your there. COA socketed with 2 poison facets, and shadow dancers, with points put into dragon flight, would really make you a deadly WW / Dragon flight Assassin. Just remember, you are going to lose significant life. 3K overall is about the best you could ever expect to get. Most bramble sins will push over 3.5, sometimes close to 4K with perfect gear. 3k is enough, but it is a sacrifice. This is the only instance where COA could be used. If your not wearing dancers, then no, shako is 10 times better then COA is.
