I haven't seen this topic brought up, so here's this post.
Why replace the public dungeon bosses in almost every location? Why? They're not needed for daily quests, the invasion storyline doesn't lead to them, and they play no role in the event. They don't even drop any special loot (and what they do drop is a joke: a bottle and 20 gold coins. All those small interior items like mugs/barrels, books, and the like could have been put in the event quest boxes, like in other events). These bosses simply invaded us, entered a cave at the edge of the map, and sit there alone among zombies, vampires, bandits, and flowers, doing nothing. It's as if they decided to take a break in this cave from their worm family, alone. At the same time, they replaced the original dungeon bosses, which means you can't complete the dungeon completely, you can't get the achievement (you'll have to wait a month for U48 to release for the original boss to return and complete the dungeon), some of the undaunted quests are impossible to complete, and some people reported that they couldn't get the clues for excavations. This useless part of the boss event ruins the rest of the game, and for what purpose? It just happens. Why couldn't they have sent these bosses wandering around the open area or sending them to attack cities? This is an invasion, why did they lock them in caves? I can't imagine what it's like for newbies who enter the starting dungeon and instead of a regular boss with 200,000 health, see a boss with 1.8 million health and just don't understand what's going on.
Give the person who came up with this a candy reward and send them on vacation.
Ps: I understand that many have already completed all the dungeons and closed the locations, and they are not particularly concerned about this change, but do not forget about new players and those who have not yet completed the entire storyline.
