Hm, I never noticed the 1 second cast time thing and I also don’t play my rogue too often. But from my experience, I remember it as cast time = weapon speed and cool down = weapon speed. So basically, 2x the original speed. I would test this, but I’m currently at school and I don’t have access to WoW. T_T

No, if that was all it was Hunters would still have outdamaged them.

The problem is that the cast time is indeed 1 second regardless of weapon speed, which meant that rogues with slow crossbows would shoot three shots for every one autoshot from a similarly equipped hunter. Aimed and Multi can easily make up for a slightly higher crit rate, but not for 3 times the autoshots.

Back when the "bug" occured, I made some measurements.
The cooldown between two possible shoots, i.e. when the first bullet hit and than the second, was exactly the weapon speed that was stated for the specific weapon. Made sense, the total time to pick up a bullet, load the weapon, aim and fire.
Therefore I didn't consider it as a bug, but rather as a bugfix. ;)

Turned out to be too powerful though and Blizzard decided to change it back to now. Now it's something like weaponsspeed + cooldown, as stated above.

Played around with it some more. Seems you get a half second delay to "aim", after which you get a 1 sec cast, and then you shoot. So I guess it is one second- it just doesn't feel like it.

The lack of a casting bar doesn't help. = P (not that it should have one)

Well, Aimed shot doesn't have a cast bar either (and it takes 3 seconds normally), but there are mods that give it a cast bar; the one I use is Zhuntertimers.

I guess someone could make a mod for it using that base code if they really wanted to do it.
