When running an 'Enemy Confrontation' explore mission, before each wave a dialog box pops up stating that we're about to be attacked. The first one I completely understand as it's part of the mission setup. Each one thereafter is unnecessary and ranges from a minor annoyance to a UI-based Confuse that only affects the player as my ship and the next wave are 11km apart and rapidly closing.
Please change the initial dialog to say that multiple waves are inbound and have the last boss wave bring up an 'Incoming Gloating Transmission' dialog, like you do with the Breen.
I agree with your grievance, but until a fix is provided by Cryptic you could do what I and I'm sure others have done. Change your HUD display so your mission message box is not in the middle of your screen and under options check the box that allows you to continue moving through a dialogue pop up.
