im all for something new but city of suffering shouldnt have been dlc it is only a unholy cathedral type mission that doesnt offer anything special or useful.
It is planned to be released in the first half of January!
I dont understand how you can name City of Suffering just an Unholy Catherdral, when you are able to farm a shit ton of relics for money+fate and useful stuff here for end game. Instead I would increase its difficulty, just so that enemies become stronger the more points you get.
The City of Suffering DLC offers a new type of game mode which can resemble for Unholy Cathedral from a certain aspect, but its design and goal is different from it and has its separate leaderboard as well.
