I actually like the loading screens. Aside from the neat art they display for each zone the 'barriers' for zones are the same ones used in FFXII which takes me back to the good old days of PS1/PS2 JRPG's.
Don't get me wrong, I enjoyed the ability to explore an entire continent in WoW with minimal loading screens but once flying was added the zones no longer felt as mystical as they once did. FFXIV may have a smaller game world overall but the zones feel less stuck together.
