I've yet to see an event, and nobody I've talked to has witnessed one either. Do what I do, petition daily complaining about our lack of events, it's now 21 eventless days since story launch.
I did see a player event yesterday that was interesting, the gm's even did a world announcement to let everyone know about it. To bad they couldn't get off their but's to get rid of the guards spamming their amnesty crap.
I have this to say to funcom, I paid for this game same as an rk1'er, I'm paying the same monthly fee as an rk1'er, and I expect to get the same product. So far I'm not.
