First try, fairly easy for me once you just avoid enemies by not walking in their sight cone, which I found short. Still, I get why people would get frustrated with how little direction is given. Problem is that we're being thrown into a completely unknown scenario with specific mechanics in a map we don't know anything about and a lot of alternative routes where you can get lost, and since every street is crawling with enemies it can get tiring. For some it'll be easy, for some not. Depends on how your mind unravels the whole situation.
Even if it's a part meant to inspire despair and hopelessness, once the mechanics become an obstacle the illusion breaks and you start feeling infuriated not by the situation in the story, but rather the videogame aspect of it. Sadly that it's this polarizing, kudos to the devs for trying new things and hope they can polish that kind of scenarios in the future. Just reserve them for very, very special occasions.
The end of the quest was kind of strange. Scions realizing too late when Y'shtola should have known the first, then G'raha realizing, then the WoL who was crawling on the border of consciousness arrives juuust in time and everything's like "ah well body swap time out, too bad. let's not bring this up ever again". The WoL doesn't even seem that frustrated after such an agonizing experience, and everyone gets over it in a flash. Even if the tower assault takes priority, seems odd to me.
