Thanks a lot, you've been very helpful guys.
Now there's only the second part: which stat snapshot is used while calculating the damage - when I hit the button or when the skill hits the target?
I'm mailny interested in this because I have Renataki's. Say I have 1.5 sec left on Renataki's and have GT off cd. What do I do?
Scenario 1: Damage is calculated upon skill hitting the target.
I delay GT and fire Arcane Shot which will get to my target in this 1.5 sec and benefit from Renataki's. GT because of its slow speed wouldn't make it to my target within this 1.5 sec.
Scenario 2: Damage is calculated upon me hitting the button.
Obviously I use GT.
I know these are some minor differences but it really bugs me.
Also despite it being something so minor it could add up to few hundred dps in favourable conditions therfore possibly earing me a bit higher rank on WoL
