Rangers were hit hardest by the quickness nerf. There are only 10 skills/traits which give quickness, and rangers have 3 of them (though one is for the pet).

Pre-patch
Assuming you used each quickness skill/trait as often as you could, here’s what percentage of the time each class could be under the effect of the quickness boon.
Guardian: 2*3/180 sec = 3.3% of the time
Mesmer: 10/210 sec = 4.8% of the time
Engineer: 4/60 sec = 6.7% of the time
Warrior: 4/60 sec + 4/90 sec = 11.1% of the time
Thief: 4/60 sec + 2/30 sec = 13.3% of the time
Ranger: 4/60 + 2/20 = 16.7% of the time, could be traited to 4/45 + 2/16 = 21.4% of the time
Since quickness doubled attack speed, these percentages were equivalent to the increase in the class’ DPS from quickness. i.e.
Guardian = 0% base (unquickened) DPS (because they’re holding a book)
Mesmer = 104.8% base DPS
Engineer = 106.7% base DPS
Warrior = 111.1% base DPS
Thief = 113.3% base DPS
Ranger = 116.7% – 121.4% base DPS
Post-patch
Guardian: 2*3/180 sec = 3.3%
Mesmer: 10/210 sec = 4.8% of the time
Engineer: 5/60 sec = 8.3% of the time
Warrior: 5/60 sec + 4/90 sec = 12.8 % of the time
Thief: 5/60 sec + 2/30 sec = 15.0% of the time
Ranger: 5/60 + 2/20 = 18.3% of the time, can be traited to 5/45 + 2/16 = 23.6% of the time
Quickness now only gives a 50% increase in damage. So the increased DPS becomes:
Guardian = 0% (no change)
Mesmer = 102.4% base DPS (2.3% reduction from pre-patch DPS)
Engineer = 104.2% base DPS (2.3% reduction from pre-patch DPS)
Warrior = 106.4% base DPS (4.3% reduction from pre-patch DPS)
Thief = 107.5% base DPS (5.2% reduction from pre-patch DPS)
Ranger = 109.2% – 111.8% base DPS (6.4% – 7.9% reduction from pre-patch DPS)
So even though the change is universal, it hurts rangers the most because they had the most access to quickness. Compared to pre-patch, it reduces the DPS of the ranger class the most. And rangers benefit the least from the compensatory buff to quickness duration because their primary form of quickness (pet swap trait) was not buffed.
Commentary
First, will people please stop saying QZ got buffed by having stun breaking added to it. That was not a buff, it was bringing the skill in-line with the warrior and thief quickness skills which were already stun breakers. QZ was inexplicably missing the stun break, and this patch simply fixed that imbalance.
If you choose to fix a problem in the game not by directly addressing the problem but by changing a broader mechanic, you have to be careful of unintended consequences of that broader change. The reasons cited for the quickness nerf were double action speed making it impossible for other players to react (I assume this refers primarily to stomping downed players), excessive burst damage in PvP, and trivializing certain encounters in PvE.
Aside from stomping, I can’t see these as referring to rangers. Rangers aren’t known for burst damage. And considering the longest quickness lasted 4 seconds, it can’t have trivialized a PvE encounter in terms of damage, since all it would do is reduce a fight time by 4 seconds. The only trivializing of PvE I can think of is the double action speed making it easier to certain non-combat things in PvE.
So if the above assumptions are correct, ranger DPS wasn’t the primary target of the quickness nerf; yet ranger DPS is what took the brunt of its damage. That’s the type of situation which can crop up if you try to address a specific problem with a general change. To fix it, you need to buff whatever it is that was unintentionally hurt by the general change. In this case, you need to do something to bring ranger DPS back up.
Playing around with the numbers in a spreadsheet, increasing the quickness duration from pet swap to 4 seconds should accomplish this. It reduces the nerf to ranger DPS to 2.1%-2.8%, which would put it on par with the nerfs to mesmer and engineer DPS by the change.
An increase to 3 seconds would make the nerf 4.3%-5.3%, which puts the ranger DPS nerf on par with warrior and thief. But ranger can’t burst like those classes can*, so I can’t see how one can justify nerfing rangers as much as those classes were nerfed by this change. (* I suppose rangers can approximate warrior/thief burst if the target stands absolutely still so both the ranger and a cat pet can whale on them unimpeded. That’s a pretty restrictive set of circumstances though.)
