Well, if you really just want random uninformed speculation: I don't think there will be many changes to the Halloween event this year since Citan's been busy with the new UI. I'll assume we'll keep the random key drops from assorted world mobs but I've no idea if the main event will remain or how it can be community fun with the new loot lock system... I can't really think of an easy tweak that will work with the loot lock. Maybe it will just stay the way it was and the first player to tag will win the loot?

I don't know, I sort of hated the loot frenzy of the last event, so I figure anything this year will be better. My problem with the event before was that whenever I logged in, literally the best use of my time would be to wait around for the next event mob to show up and die, so I could loot it, and that got boring pretty fast. I hung around long enough to get all the available notoriety on 3 characters and get bat-diseased on my main, and then I pretty much avoided logging in during the rest of the event. I opened a few chests, but I think I still got 25 universal event keys sitting around somewhere... It just seemed like way more loot than was actually fun to me.
