One of the features of Battle Sprite update was the difficulty setting, but still, for lot of players -who learned to dodge- it didn't added any challenge.
In nutshell: This difficulty setting (normal-advanced-elite-classic(?)) would add pre-nerf monsters -of course with better loot.
This means:
-inceased AI (no more brain-dead retarded infant enemy like they are now)
-melee attack for menders
-instant Retrode lasers
-monsters tracks the player, so you can't just avoid every single attack by taking one step to the side
-every monster family is a real threat
-no more "it's too easy""no challenge" complaints
(the list is not complete, if you know something about the pre-nerf monsters, please comment it)

Still might not be a challenge to veteran players. I myself have been here in 2011, where Alphas were feared, retrodes were incredibly annoying, devillites even more so, and this will get easier after a good amount of experience. Then, we will beg 000 for harder and harder content, while those newbs can't even get past T1 without using 20 SoLs. And what will this be called?
