My question is why would you care? I play the class I like because I like it and I like to play with my friends. People can brag about achievements and post screenshots of their amazing stuff all they want. If that is how they have fun, great! It has nothing to do with me at all though.
Also...
I prefer to keep things as close to vanilla as possible but.... Since it is already kind of mucky already I think it would not be the worst change. Spreading the best drops out through all the episodes does make sense, as well as moving odd drops to more appropriate difficulties like suggested...
I think these quest should only be sometimes too. They are fun and fine for events and maybe emergency quests like PSO2.
They seem a little bit silly and not much like the rest of PSO at all. POD and Max Attack are supposed to be the special ones right?
