Scaling to 16k. as old tales are introduced 16k was a very high value (think around 19k was max to that time).
Now 16k is meh and further sacled down, dungeon is impossible.
So the beginning scale in relation have to be around 23k (now that 27k is max) not 16k il.
You can see very clearly that on run1 with artifacts all is fine (even if at 16k il), but if artifacts are forbitten in run 2+ the group has a hard time. Thats where you can see that more then 60% of damage comes from artifact and that is bad.
its not anymore a player skill test, its who has better Artifact (and artifact scales with power from char). And that is on all other contend the same. This makes high power low stat values on all stats the "best" Players, cause of high damage scaled artifacts.
IMHO the wrong direction of this gamedesign.
Hope you find a way to solve it for running event, or extend (repeat) event after fixing it.
The dungeon is broken, due to scaling, first you are scaled down, and it seems that at each difficulty, the enemies become tougher and hit harder, WHICH SHOULDN'T BE A THING, the difficulty is not supposed to boost the enemies but to nerf you by disabling your artifact, making ur cooldowns longer, decreasing ur defense and power by 50%, but its rather nerfing you and at the same time boosting enemies.
Cryptic, you are making this event not practical for decently geared/skilled "casual" players, and pandering to a base of like (maybe) 10-35 ppl who can get an artifact here, let alone the additions to the artifact, or the scarf/sash ...
That defeats the entire purpose of such an event, which (IMO) could be around LOMM level (or slightly less difficult), but instead is turning off lots of folks (most folks I talked to are not thrilled, and are doing other things in-game instead).
I really love this game (didn't mind the class tree overhaul in Mod 16, for example), but Cryptic you're making it harder and harder for me to play/support this game, if you have such a broken event.
Eliminate scaling in this Tales of Old Event, and I'm quite sure that most of the fanbase will be quite happy with it.
If you get dissconected by the server, you get kicked out of party and send to city, wow.
