Like it or hate it one of the biggest things that made FFXIV (and FFXI) unique compared to other MMOs out there was the playability like an offline game that just happened to be online. The character controls (when used with controller) functioned exactly like the Final Fantasy offline counter parts.

It seems that in ARR they have adopted a more western "mmo" style control scheme where the mouse/keyboard is the predominant method of input. Instead of freely running around and locking into the target which then changes you to a battle movement configuration (down backpeddles, left and right strafe) the player now is permanently in the "S backpeddles, A and D side step, and W moves forward" regardless of whether in battle or not.

Personally I despise this popular mmo control scheme because I prefer to play with a controller. My only hope is that when switching the PC version to from keyboard/mouse to gamepad mode it will also switch the mechanics and UI a bit to reflect the current control style.
