I actually like limited events, as long as they switch it up evenly on who can participate where.
Why you might ask? Because limiting these events = less participants = higher chance of victory.

TBH I have no idea whether SE is switching it up somewhat evenly, I don't really follow these events much, although my FC did participate in the video contest and we got the mandragora chokers. But if they do, it's all fine and dandy with me, if they don't then yeah, there is a reason for being unsatisfied.
