Interesting...what does intra city travel mean, the Windurts npc warp or the different exit zones from player housing or soemthing entirely different altogether such as atheryte to atheryte?
I have felt the cities in FFXIV are smaller than those in FFXI so intra-city travel hasn't been necessary. Having said that there are some annoyances especially blind turns which can be missed at Limsa Lominsa and Gridania, even then I fail to see how intra-city travel will solve that.
My guess is that this is in preparation for 2.0 where cities might be larger than they are now. Or maybe they'll force walk all players in town so that intra-city travel might be necessary in you are in a hurry :P (seriously, why is every running around in town anyway - what's the rush?)
