My only complaint on events is when they overuse FATE-based events. Those aren't really fun anymore after you do them so many times. I'm really happy the Valentione's event and this event aren't FATE-based.

Plus this event looks really cute, and I can't wait to get my hands on that minion, it's one of the cutest things I've seen! Events for seasonal things don't have to give anything major. That's not really what events are for. They're supposed to be for fun and to celebrate seasonal holidays or special happenings or what have you, and everyone is supposed to be able to enjoy them.
