This has been annoying me for a while and I can't be the only person who has experienced it. After FoK'ing and applying rupture, I tab targets and FoK again but most of the time the combo points don't get applied to my target but to a different target (I am guessing my previous target). The combo points are definitely building up as if I pop Redirect, they appear.
How do you guarantee that your FoK generated combo points are applied to your current target?
