The Objective Complete, Quest Reward window pops up right in the middle of the screen obstructing the view of our character who still has mobs to kill. This is extremely annoying.

At the very least have a clicky option in the quest tracking hub that we can click on to retrieve our reward window.
If not perhaps have the window pop up when we click the portal to leave, choose our reward then click the portal again to leave.

At this point anything would be better than blocking our view during fighting.
