Since the launch of Legendary Dungeons, Nexon has been keeping track of player input on their performance. This week, they revealed that changes are in the works for the Dungeons. These will balance the difficulty and make them more enjoyable.
Unfortunately, details on the adjustments are still being worked out, so we won’t know exactly what they are until the update on November 16. That said, the CM team is responding to questions on the forum post and have confirmed that things like gear and item drops are also being looked at.
If you’d like to read through the post thread — and possibly get a bit more information on the update before the 16th — you can do so on the Riders of Icarus forums.
