I have 600+ hours in this game and had 5 playthroughs and every playthrough I romanced Astarion. non-ascended Astarion once and rest of them were all ascended Astarion. It's safe to say his personal quest line alone kept me wanting to play the game over and over again (aside from the game being awesome itself). What Patch 4 did to Astarion's ascended romance scene and his character model and the kisses animation had a triple-kill effect on my overall experience of my 6th playthru, which again I romanced Astarion. Now I'm just heart-broken, and registered an account here just to vent.
Right there with you, I will continue to holler from the rooftops until they get it fixed!
