It was a little better before the 2.5 update on Feb. 15th (?) when they removed open world drops. Since then it's been complete silence and just more issues every patch. One thing they did fix with 2.7 at least was the needed low level stigmas, but it's too late, most people already quit or moved over to start in EU Classic which launched recently.

Not much has changed since I posted this, have a look at broker for manastones for example.
I don't think they have much staff left working on this anymore, look how they even misspelled the new server name (Nezekan/Nezekan) directly in the game, or these stigma boxes.. assuming they copy/pasted the templar string to replace the class name for the rest, and didn't even remove the original word, something so basic, makes you wonder what kind of QA/QC they have (0). New class can't even use teleporters. New server is emptier than the Sahara desert.. (how could they ever think it was a good idea to open a new server with the main one already empty ????).
It baffles my mind that this is a real company, this game atm feels like it's run by a bunch of kids toying around with a private server.
