Hey there and welcome back.
Im new to the game and have been playing since march or february. Even so I can answer your questions...
Dont know for sure, but is a lot for elves.
It still is 60.
I had problems with it at the beggining, but for now they work satisfatory, although I dont think it is fixed.
Still per second.
Plus, they worked on some out of sync issues, added a tool on searching someone for pvp and coop (now you can search for players name) and they are working to improve path find and lag and maybe implement some system that allow us to trade. That is all I think.
See you on battlefield.
