Dinged 50 last night, really enjoying the game. Playing a warlock, went with something completely different than what I would normally play. Haven't played an arpg since the first expansion of Grim Dawn came out so it's refreshing.
Was in a queue for about a minute last night before I could get in, not a big deal but servers appear to be stable now, haven't experienced any disconnects or slow zone transitions over the last 2-3 days so I think they ironed out the worst of it.
I'm getting close to the last chapter before the end game stuff but apparently there are a few story chapters missing still that will be released later, maybe during the next cycles. Looking forward to try the end-game stuff. They made a post yesterday talking about the plans for future updates and it sounds like they will be adding a lot end-game stuff. Right now you can find posts around about end-game lacking but I think it's mostly from EA players that have been playing for while.
Overall, for a 45$ game, I'm happy!
