Been asking for this since 1.x... originally for my PLD and BRD, but now just because I still have yet to see a reason not to. It seems silly that I can have a weaponskill at 2.38 GCD, but Flash remains at 2.5, or worse, that no Song cast-time reduction make Skill Speed even shittier for Bards than it otherwise would be.

@Pence
At current we have Skill Speed, Spell Speed, and Attack Speed (affects casts, weaponskills, and auto-attacks).
They could simply make a Speed stat on gear which then affects both the Skill Speed and Spell Speed stats, such that future abilities similar to the original Fey Glow / Light would still be able to affect those stats separately. I suspect though that the reason they did not do this is because they wanted such abilities to favor Speed stacking less, and to provide more universal support during burst, rather than having to decide between casters and physicals (which is now mostly a MCH thing).
