So, what are people's thoughts? I'm becoming more disillusioned with step the more I use it - historically it's been great for two reasons; eating traps and focus-step-kicks. The problem is, any decent hunter will root you before trying to land a game-breaking trap so I'm rarely getting a chance to step my healer. It's true that Narrow Escape will be cloakable next patch, but you'll still only be able to step 33% of the traps (assuming you're not out of LoS or otherwise CC'd or didn't use step offensively or cloak offensively).
As for step-kicks, how many kills this season have you made thanks to a step-kick? I rarely ever have step available during kill opportunities because I've had to use it to connect with the kill target after they've used a mobility talent (disengage, safeguard, heroic leap, leap of faith, portal, gateway, displacer beast, transcendence etc). The times I could have stepped, it hasn't been needed - smoke bomb and blind are enough (as is all the other CC brought into the game).
The only other benefit I can think of is it sometimes lets you get back on your target after a z-axis knockback (though not even this is guaranteed thanks to LoS issues).
In 5.4 the alternative is a talent with no cooldown that you can literally spam. 170% speed whenever you're not connecting with your target, refreshable after a GCD if you get slowed.
Are the three reasons to take shadowstep enough to make people sacrifice the extra mobility a spammable BoS brings? I can't help but think shadowstep is a relic of pre-cata gameplay that people only take because it used to be very strong. It's sad to say but imho, all the new abilities introduced over the last two patches have made it subpar in comparison to 5.4 BoS. I might take it on Blade's Edge vs teams with a hunter but no offensive casters/dk/rdruid, but I'm not convinced.
