On ffxi yes we used windower. But I only used it to duo/tri my characters. Which in this game you can only play 1 character at a time. Also didn't use voice chat. We used calls. You had to research fights. But I Also played on 360 with keyboard and macros. And still enjoyed it.

Look console players don't need these add-on's. And they complete new content. Would I like or use UI add-on's 100%. So would some others. But point is we can't. ACT,UI and positioning software gives you an advantage over consoles. And that isn't fair. It's as simple as that.

Also hope SE adds some of these UI add-on's soon. Also FF MMO never had bubble chat. And I've been playing FF MMO's since FFXI launch. And we've been fine.
