1. That bit's out of my control. We've literally gotten feedback saying we have too many Gamemasters and not enough of other people, even though they're what we need most of. They're the people that host the events, and it's not something we force them to do. If they don't want to, then they don't have to. We do have at least one Deputy online at any given time, but not everyone wants to host events.
2. The no new content thing is most likely because Ol'West hasn't had a dedicated developer since I left last time around, as far as I know/have been told. Orange and Jeff were the most skilled developers. Orange made the pet system, but his life got too busy to allow for Graal. Jeff works on Era now. There will be things coming out, but much like the shield it will all just take time. The magic ingredient~
3. I brought this up in a different thread. Here's the relevant bit.
".. I think we need 1 more base and all these gangs like peace stuff what is that and .."
-Calm down there partner. I agree that the bases need some sort of change, but that won't happen until we come up with some silver bullet(s?) to help "fix" (read aloud as "change") the issue. I'm sure you and everyone reading this knows it, but players in any game are really damn good at finding ways to break intentions behind systems and changes. No system is or will be perfect, but I'm not planning on making split-second choices about something so important to the game as a whole.
4. The 2016 GST was a bit of a mess. It was fun, but hard as hell to pump out in such a short time. It was incredibly buggy, as well as the livestream portion of it being quite messy in its own right. I don't remember who was commentating with me, but basically the guy we wanted to do it just wasn't available, and I'd basically spent the entire previous night getting the code up to snuff as best I could.
TL;DR/In short, I don't think we'll have any big events quite like that in the near future.
Maybe a long time from now. It's not something I've considered at the moment, since I'm currently spending most my time fixing issues on the backend that most people don't even know about since they aren't a visible part of the game.
