I agree with the Japanese player post Reinhart quoted.

I really wanted to participate in these, camped them for hours..for days..for weeks.... Spent a lot of wasted time dropping everything I was doing to port to town to town and wait some more because someone said they saw it there and it may pop. Still haven't seen one of the live events except for one newspaper npc that gave me some usless fireworks.

This wasn't what I anticipated when I renewed my subscription, and I don't feel like I am able to participate in what was promised to me if I did renew. It basically made me highly regret paying for this month and convinced me quit after this month's time is up.
Yes, I know more things are coming but the likelyhood of me getting what I paid for out of it is diminishing every day I log on. The random events aren't that big a thing to most people who may not understand my level if disappointment, but the way I see it is there are about as much things to do in the game currently as fingers on my hand. And the fact that there's finally something new and unique going on that I'm being denied just makes me turn off the game and switch to a different one with more instant gratification.

I really hope that the dev team changes their mind and makes these events and future ones more predictable. At the very least make them more frequent with a city wide announcement that it might pop in the next few minutes, maybe even have it pop in all 3 cities at the same time.
