Something as gameplay-altering as Wanderer's Minuet is very unlikely to be minor. It'd be a wasted ability if that were the case.
Chances are you'd need to be in WM for most encounters unless the fight is extremely movement-dependent in order to maintain optimal DPS. Depending on how Skill Speed affects melee casting, BRD may find value in stacking skill speed (though from what I remember, BRD is currently dependent on crit for procs, so that may cause issues in itemization).
I'm guessing even the game's built-in ability queues isn't doing much to help those with longer ping times, then.
