Mine still shows "Add Reply" button next to "New Topic" button (below) and "Reply" button next to the "Edit" and "Quote" buttons.
IF these are what you mean by full reply and fast reply... they've both always been there, right where they are now. (Moving them around isn't something we can do easily, and it's the kind of thing we'd have to re-do with every software update. We learned the hard way not to tweak things too much.)
IF your browser's showing something different than what I described above, you're looking at something I'm not seeing at all.
