While comparing Endless Walk with any other option, please keep in mind that the set bonus is not the only plus; Compass Rose has +1 primary affix. In my case I was able to find one with dex+chd+chc+AS+socket, which I believe closes the gap, might even pass the F+R with a few digits. What you really need to consider is if you can manage to increase uptime of EW damage bonus, because UE requires a lot of dodging/moving due to fact that it hasn't got a pet+sentry army like Marauder or damage/toughness trade off tolerance like Shadow set. Besides the fifth passive is more essential in achieving higher output than it is for the other sets. UE is also the least punished set for utilizing a generator which all favor using F+R over EW "for" UE builds.
