Time to read the thread dude. The main reason why is that their old, cross-platform, working software was abandoned for a buggy, windows-only software. I think the majority of the old players simply cannot connect or when the do connect there are too many bugs.
The old software was a lot less stable than the new one. When was the last time you actually logged on?
Last time I logged in was last time they had software for a system that I have access to. I think it was in December of 2014, IIRC. You can say the new software is "more stable". But I wouldn't know because I've never been able to get it to work at all. I tried it with WINE and they laughed at me (upthread).
the connection problems are nearly non existant for me and most players on the site, sure disconnects and bugs happen from time to time, but I'd still ratehr play here than a site that steals and cheats their players like Betcoin.
Ok, I'd rather play at swc too, but they stil (after 1.5 years) haven't come up with any software that I can run.
