i loved the plot at Wysteria, i found it so entertaining my favorite part is how it is sort of a "knockoff" of Wizard City with its "off-brand" school names that are very similar to the original schools
the world design is also rather appealing, and there is lots of sun which makes it better for my tastes personally
it's unfortunate that Wysteria is considered a side world by many, and that people often skip it. i don't blame them though. i think through all of Wysteria i probably got 1/4 of a single level worth in XP at the time i did it. it's also rather short, taking me only about 2 days of playing to get through all main and sidequests.
i hope that if Wysteria ever got rebalanced or edited, the devs would make it more worthwhile for players seeking to gain XP and levels, so that more people can enjoy it and feel like their time (and money) is well-spent at Wysteria
