Every new festival, the announcement tells us what the events are, but never what the rewards are. THe few times I have participated, I got nothing useful. I give up before I get any zodiac items, or for that matter, anything else I actually find useful. I'm not saying they are useless to everyone, only that they are things I have no interest in acquiring.
Now there is some kind of "speech" reward and a new currency. I don't understand the usefulness of either of them. Can you try going just that one extra step for once, so I know where I want to invest my time? Otherwise, I will continue to find all of these events uneventful.
