A lot of the things you're complaining about are also in FFXI, a game I understand you really enjoy... any reason for considering these things gamebreakers here?

I know that this is a PC porting to PS3 but it is absolutely a console game as well as a PC game so regardless of what platform the game is released on first or ported to, it still has to be a game that is playable on the console, so that will always limit things.

EDIT: Of the things you mentioned, the patching service is workable by torrents which I see as a good thing as it increases download speed - admittedly, you do need to know how to work a torrent system, but if you don't then the existing system will still work, just slowly (like all patching systems I've dealt with over the years, it must be said). Patching has actually been getting faster and faster when using the default system, it should be noted. I imagine it would increase in speed even more as more people get involved, as with most torrent systems. The chat is an expansion on what we had in FFXI, where you had no choice but to have everything in one place. No, you can't seperate to individual chats here and there, but I don't mind as I'm used to FFXI as it is. I suppose you could say it's a flaw but I think it's more of a lack of a bonus feature.

I've experienced fatigue which it should note applies only to class levels, not to your physical level. I do just fine by switching between classes and, when spending time doing things aside from my main class, whenever I go back I'm able to level it up for a while once more. It's not a huge deal, really. It does limit how fast you can get to cap your class level, but you'll still get to cap in the same time as everyone else and you'll still get to the cap well before the cap is raised, I'm sure, if you're playing that often.

No custom markers or party members on a map is pretty crap, but it's certainly no gamebreaker. I've not had trouble finding anyone so far, but then I don't spend a large amount of time looking for specific people yet, and with Danielle I can see her screen anyway.

I haven't had trouble with the targeting system. The mouse lag was bad at first but I've not seen it much at all lately. I know that in the program there is actually a HARDWARE_MOSE=FALSE option which can be set to =TRUE to remove any lag whatsoever using third party software, but the fact that the option is there at all in the program means it will likely be implemented as an option in the config/menus somewhere eventually - as people have pointed out to me, it's likely they have not enabled it at the moment purely because they want to test the software mouse in the Beta, or that they haven't fully tested the hardware mouse internally, which is perfectly understandable. Hopefully we'll see that option listed in the menus/config sooner rather than later, but for me the lag isn't horrible at all. When I move my mouse, the cursor moves at the same time. *shrug*

UI lag is horrible. Especially when trading or crafting. I'll definitely agree with that, it's the biggest problem of all at the moment.
