Or at the very least do not nerf scaled VETERAN dungeons. They are fine, they pose a challenge, they are easily completable, even by scrubs. Only the gold keys are difficult to get. BUT GUESS WHAT! It shouldn't be easy to facetank the final boss of Fungal's lasers. It shouldn't be an easy DPS race to kill a vampire siphoning health off of five people. It shouldn't be easy to kill a high kinlord with several deadroth running around, it shouldn't be easy to kill the engine guardian while choking on poison. It shouldn't be easy to kill a legendary titan while he spawns his favored healers and it shouldn't be easy to kill a lich lord with four wraiths running around.
Hell none of these things should be easy WITH OR WITHOUT their special conditions.
