Witch/Wizard are still broken on ptr.
Currently on both the live and the ptr version, if you go witch a witch/wizard and try to kill monster with a “Flow” skill you won’t get any credit for the kill aka XP/loot.
On the live server I used a armstrong skill reset to remove the flow from the Shift + F skill of the Witch, i killed 10+ groups of monsters with Shift + F, all of them gave me XP/loot, then i tried with the flow, and they started giving me no xp/loot at times, it doesn’t happen everytime but it does happen very very often.
On the PTR I tested it with flow active only, since I don’t have access to the Armstrong skill reset here, and same thing, sometimes they give me credit for the kill, sometimes they don’t give me anything at all, specially with monsters that are further away from you.
That’s not only limited to Shift + F, all pet flows have this issue for what I’ve seen.
My only explanation for the issue is that the Pet actually gets the kill credit since it kills the monster before you actually make any damage to it, but this is 100% game breaking since it makes the Witch/Wizard class (not sure about the others) pretty much unplayable in pve with flows.
