As someone who plays a lot of Bard despite the fact it doesn't perform well, my primary gripes with the job boil down to less damage than the melee jobs who have (arguably) less demanding rotations and the fact that generally speaking a raid or group or whatever isn't going to miss my songs and would rather just bring in yet another melee or even a caster. The buffs a Bard provides just feel too inconsequential to even bother with bringing one along. Realistically a party isn't going to notice a 3% increase to direct hit, or a 2% increase to critical. Why Wanderer's and Army's just isn't a flat 5% to direct hit and critical will always baffle me. I can get Mage's only being 1% damage increase, seeing as Dancer can give a constant 5% just to one member of the party, but the other two? Is there any (valid) reason for Bard to offer so little direct and critical hit when Dancer can also give both at the same time to a Dance Partner on a 120 second cool down?
This brings me to my second gripe: Bard still suffers from having Dancer in the game. A Bard's buffs and utility got neutered as soon as Square decided to add a new primary support class in the game. There are a myriad of other things a Bard could buff. Mage's could offer a boost to Determination instead of just damage done, and this would have the side effect of affecting a healer's healing output instead of just more damage. Wanderer's could offer a 2% increase to a primary stat. If Blizzard can figure out a way to make a buff or a food item that says, "Increase primary attribute by X% amount" and have the primary attribute be increased no matter what class receives that buff, surely its not too hard for Square to implement something similar. Army's could offer a boost like 2%-3% decreased damage taken. If they want to keep Dancer as the more offensive support fine, but don't also slap Bards with the exact same buffs but at lesser values just because a Bard's buffs affect more players, especially since those buffs are tuned so low that parties would simply rather take another melee and a Dancer who'll supercharge said melee better than a Bard ever will.
Finally, Sidewinder feels bad because its nothing but another button for damage and a strangely long cool down. I would prefer Sidewinder to just be removed entirely, but honestly at this point I would take the potencies for Sidewinger and Refulgent Arrow being swapped. It feels really bad using such a boring weapon skill in conjunction with Barrage, but this combo happens anyway because Sidewinder is our hardest hitting attack outside Apex Arrow and Blast Arrow.
At the end of the day, I guess those of us who play physical ranged will just have to wait and see what exactly they end up doing when they supposedly go to look at the "Ranged Tax". More likely than not its going to be nothing but very tiny potency buffs that aren't going to do much of anything, but I guess something is better than nothing at all at this point.
