My favorite thing so far has been server crash recovery. It has come a long way where, instead of waiting 10 minutes for the server to recover, they've gotten it down to around a minute.
At the worst, if you get stuck on a server that encounters a crash loop, you'll at least have short windows of opportunity between crashes to make it to your ship's bed so you can safely logout and switch servers.
30ks are almost a thing of the past.
