Will be moira/zen, Moira/Lucio mainly. You'll have Seoul run Ana a couple times throughout the stage because ryu loves ana but that's it. It will be alot more triple/quad tank on attack which will be Moira/Lucio and you'll see Moira/zen and Moira/Lucio on defence. You will probably see more mercy than ana even in stage 2.
Won't see much of ana unfortunately. Too many sheilds, DM and barriers, she will barely get any healing dome because of this. Ana is my favourite healer too.
