All you have to do is log in once a day and get all the events in about 5 minutes. I study mirkwoods and to put that in perspective I got 23k exp.. and a full study 24/7
Instead of this nonesense, how about adding "curios" that give positive exp with no lp, and very low study cost?
This can also balance mirkwood, as you might find it counterproductive, and will make mirkwood early game only, because you may want fast lp early on, but will want to replace it later for efficient exp- lp curios.
