Or, any Bard who liked being in a position to immediately react to mechanics and doing so without dps loss, and moving to the next optimal position when it changes. That's a very frequent use of Bard mobility that doesn't fall into "no reason whatsoever", I would think. It's something that will nonetheless be done, bit by bit, with WM, but has certainly been effected. If the implementation of Bard's new '3.0 DPS mode!' could magically cut down on 'stupid-movement', leaving only 'smart-movement', the practical among us would never have complained (even if others would have on principle of some vast, free Bardly spirit), apart from, of course, the Bloodletter-loss, oGCD snags, double-weave being limited to rare procs, etc. (but nevermind those). It's quite often that being the first to be at the ready, the most mechanics-accessible, etc., that Bards are missing, not just the ability to run circles or drop AoEs on their mages on drunk night.
But enough gloom. There is a benefit to WM that people don't mention as often as they easily could. When, as a Bard, one is told to do mechanics, s/he can make like a BLM, give them the finger, answer, "Casting," and point at the SMN (as long as he's not in Dreadwyrm stance and spamming his precious Ruin IIIs) to do all that in his/her place. Or, with no SMN present, blow up alongside the BLM, because that poor Mage probably never could have been quite so caster-ly in the first place if his healers weren't sprinting about and his Bard intercepting for him a game ago. Luckily, this seems a non-issue in 3.0 Savage. We just don't really move around much for most Alex fights (sidestep out of AoEs, approach new spawns, in and out a bit on a tether, claim a new intercept point). It's a good deal of bonus damage with little to no consequence. Yep, dodged the wrench there. Yet the Bard pain comes from realizing that you're still not much closer to 'real' dps than you were back then even when you're as caster-ly as possible. The damage bonus is real (not nearly 30% outside of AoE spams, but certainly very significant), and yet a good Bard now is no closer to a good melee than he was at the end of 2.x. Yet we can't be any closer or we wouldn't be 'support' (e.g. feeding casters so they can pretend to have melee-level dps), so we're stuck with a massive change just to keep from falling far further behind? Hmm. Hmmmm.
.....To be clear, this is coming from someone who generally finds WM gameplay more 'fun' than 2.x Bard gameplay. Not 'more serious', not 'more focused', only 'more fun'. I like its twitchy little idiosyncrasies. 3.0's Bard 'DPS Mode' ability could have come in a more fitting and/or interesting form, and could use some smoothing (Straighter Shot, etc.), but for the most part WM seems sufficient. But I do find it silly for WM to be called a true buff to Bard dps. It is little more than Bards holding their status quo in dps, and at gameplay cost. For it to be a buff, we would have had to gain dps-increasing abilities on par with the other DPS jobs first and then gained WM atop that. (Not necessarily in that order of abilities gains, ofc).
