I haven't had a single disconnect issue. No memory leaks, or any issues really with stability for ffxiv. And it's not just me and my awesome super-computer, either. My kids with mid level gaming machines haven't had any issues, nor the gf with her crappy hp laptop that barely runs the game on low settings.

So perhaps the select few that are having issues are doing something wrong. Just a crazy and wild thought. But you could also keep yelling at SE to fix it, even though it may not actually be their fault. You could post your problem, your configuration, anything that seems to trigger it, your installed software with versions, and how many viruses you have due to programs that people like to use like bearshare and limewire. If you're having crashes, try a clean wipe, install only minimal software, play for a week, and see what happens.
