I've seen an other amazing update from Gamnin incoming to Vigilance :
The numbers are good, but it is really important to notice I think that this update will improve our managing of threat generation during rage generation gaps !Vigilance will soon transfer the 10% threat lost to the warrior. It will also have 3 charges to curb using it on targets that are being hit constantly. We’re still polishing this element to get it to feel right.
Can someone confirm or not if it has his own GCD ?
Wait & See...
