My suggestion: Remove the delay for crossbow attacks when moving like in OSRS. This recently has been done for the Vengeance spell and I also would like to see this for the crossbow attack.
Reason: This delay is kinda annoying when you get red/white portals at raids 1.
I am pretty sure this is how it is in OSRS, I didn't touch either of the animation files for vengeance or the crossbow attack. That means that the recent vengeance change was done by Jagex and not me, which also means that this is probably how it is supposed to be.
