Up to patch 79, dungeons were fun challenging, and required you to have a minimum of knowledge to enter the dungeons, and, even when overgeared, players still had to watch out for mechanisms, giving the dungeons a feeling of challenge and difficulty making them fun to tackle on even when the gear level is way high that the dungeon's.
Then, patch 80 came out, and decided to add the completely unneeded update to make every single boss deal close to no damages and to even do the job for the players by warning about everything, making most dungeons plainly boring and tasteless, that no one would ever farm if they didn't have to.
What exactly is the point of having over 20 level 65 dungeons if about 18 of them is necessary, tasteless and not fun ? And when a dungeon is even a tinny bit of a challenge as a result of these updates, it is an hell to get any party for it because people are getting spoiled by how dumbed down and easy these dungeons are. I shouldn't be able to take an ilevel 439 character in dungeons of ilevel 453 and higher and still survive, yet, I did.
Maybe some people enjoy how easy TERA is as of now, but, I'm pretty sure there are a lot of players that don't enjoy it and are not having fun doing dungeons right now, which is pretty problematic when dungeons are most of the pve endgame.
As of now, even AQ and Bahaar are too forgiving, allowing you to take damages left and right without even dying, and, honestly, patch 80 completely killed the entire concept of Slaying runs before the removal of crystals with how easy it was because simply face tanking everything without thinking was more efficient than having upgraded damages but having to dodge ...
So well, basically, some players wish to have fun when playing TERA by being challenged once again by some brutal bosses and mechanisms, and, right now, we have absolutely nothing and are pushed aside. What is the point of making the game easier to access to new players if to reach the point that you have to sacrifice away the old players and make it so there is no one to accompany the new players out on their journey ?
