Shadowstep is situationally amazing as a skillshot in combat, but claims about rogues having S-tier mobility in any other situation are mostly exaggerations compared to what other classes are capable of baseline/with bare-minimum investment. Sure, grappling hook is great, but is it as good as FSK? Double Shadowstep is great, but what are we giving up to get it? Hint: it’s damage. Sprint is fine, but hardly broken. You need a point to bring it to 1-minute, and it becomes a 2-minute emergency reserve ability untalented. Rogue mobility is simply okay.
Claims about us being unrivaled in movement, utility, survivability, and damage are basically myth at this point. That which we do have are things that we need maintained 90%+ to live fights. Meanwhile, other classes - mostly hybrids - have similar or better of each layered atop flatly better overall baseline survivability.
Additionally - and I’ve mentioned this a few times elsewhere - stuff like this preamble to the Ret rework just digs us further and further into the make-believe of class descriptions. Our mobility is fine, but hardly the gold standard.
