1. First boss doesn't cast https://www.wowhead.com/spell=196587/soul-burst at 15% hp. Now you can just kill him down w/o even worying about the adds. No matter if u kill the adds or not he should cast it at 15% hp.
2. Trash after 1st boss after the spiders when you go up the stairs (The one under Illysanna Ravencrest ) doesnt work the way it should, you need to clear the whole room then wait for the last wave to jump from above and then you are supposed to proceed and the door opens(the door on the left). Now players can just open the right door and skip all that trash which is..... stupid
3. Charging the 2nd boss Ilysanna as a warrior will send you under texture back down to the lower room.
4. Last boss Latosius abilities are totally out of order. After he shows, in 10s he should cast https://www.wowhead.com/spell=202019/shadow-bolt-volley and 4 seconds after the shadow bolt cast he should give every player the hp and damage buff and then start with all the other abilities. https://www.wowhead.com/spell=199193/dreadlords-guile doesn't work at all.
5. The falling rocks sometimes spawn 2 next to each other which is really annoying cause u cant really pass. The are not supposed to stack.
