I got very lucky. As soon I was connected, I got invited to a 14 days survival in day 10. Lowbie one, so when we completed it, I got the Hydra weapon. Managed to play a bit more and got another 2 storm llamas. One legendary heroe in one of the llamas.
At first the game was superslughist, but then they did something, and now the game feels solid 60 FPS. What the hell? it feels almost like a different game now, everything is smooth.
I like the event. Don’t like much the actual survivor thing. It simple take too much time. It really needs a button to allow players to vote to skip to the next day. The modifier are really cool and add a lot of the game. This + the new monster spice things by a lot.
Not everyone is equally happy and I read on the forums that many people have a lot of problems, so YMMV more than ever.
