Here are a couple things I came up with for the new strike. (Boss fight) The safest area is the corner at the front of the room but I'm sure most of you guys figured that out already. Everytime omnigul shrieks, a new wave of enemies is spawning. Their is a ledge on the right side of the room in the front that keeps you safe from all the thralls that spawn, as well as cursed/hallowed thralls that will walk out of doorways inside the room you are hiding in after a couple of waves. Hang out up there and pick off what you can each time a new wave spawns. Also use this as a fallback point anytime things get dicey. Looking across the room parallel to the bridge, a hallowed knight spawns directly across the room, and two Knights spawn on a ledge up and to your right (outside the room). These three Knights have to be dealt with before you shoot omnigul because otherwise they will constantly lay siege on the doorway of the room, and you won't be able to leave the room to shoot omnigul. DONT DIE ON THE BRIDGE. It will be hell for your teammates to revive you. That's all I got. Hope this helps.
