Some people may want to take the easier road farming normal mode alone when they can't clear higher level manic modes, especially solo. Why exactly like that, who knows. Let's not hijack the thread though.
As I noted in my example, you're being sent back to do dungeons almost ten levels below your level, at that stage, even manic would be easy, but normal is a joke, and feels like a waste of time. Also I was asking for the capacity to finish the quests at the given difficulty level, or higher, which would still mean people could do them at normal if they wanted.
Also hijacking a thread would be if people went off on a tangent to talk about something completely unrelated to the topic at hand for a number of posts. Something like I was saying, and you're responding to is completely on topic, so would not be hijacking.
In case nobody noticed the Normal and Hard difficulty actually gained the biggest boost in this update.
So what you are asking for is and was already implemented in the patch OvO
I actually really liked that about it, I went over it on the live stream a while back.
I was happy about it because my girlfriend is now more likely to get to max level since she doesn't need me to do manic quests with her.
Also I went from 58-60 using Carnivore Park Episode 3 Hard (pretty certain)
Instead of what used to be the largest EXP area "Meat Factory".
Not only Did I end up getting around 5mil more EXP per run this way but I also completed the runs much faster. If I am not mistaken I was getting around 11-15m EXP per run with EXP gear, titles, etc.
That district also has 3 RPLY quests so you get bonuses for killing the boss
Basically normal and Hard are much much closer to manic. I'll look for the Spreadsheet I made.
