One of the builds is quite a bit like my rogue's new leveling build (as well as Chris's latest Build Shop rogue build), so I guess that means a number of other players love the new Cheat Death too, and not everyone thinks Shadowstep is a waste. I'm not a high-end raider going for the top damage, or a PvPer going for the ultimate skill combination. I just like zipping about all over the place every 30 seconds while questing or doing normal instances, and I figure whatever I lose in damage in order to get that is more than made up for by the "wheee! teleport!" factor.
So if you're the type of rogue who suddenly feels tempted to cause lots of hemorrhages, this guide could be a handy starting point, or else a nice way to measure up your own personal build against what other people thought would be good.
