A year or two ago, before any detailed Aion info came out, the first thing that worried me was the movement controls, Korean MMOs have an absolute requirement that says the game must be playable with click-to-move. What I had read was that since most asian MMO players play from web-cafes, they usually have one hand on the mouse and another with a cigarette, a drink or food. Hence the click-to-move requirement.

I won't lie: I hate click-to-move, I don't feel in control of my character because I can't control the direction he faces and the direction he travels independently of each other. If Aion was mainly designed around click-to-move, then it was definitely not going to be my cup of tea. A year passes and more gameplay videos appear on the web, from the earlier videos it was obvious that Aion allows keyboard movement, but I was still uncertain if it was responsive and smooth instead of some afterthought for the western market. Until a few days ago.
Not only does Aion use keyboard movement, it is perfectly responsive, has smooth direction transition, and separate animations for diagonal running, forward running and backtracking. Now this sounds like a standard that every MMO should have, and most western MMOs in recent years do meet this standard of smooth movement and seamless animation transitions. In all honesty though, eastern MMOs do not have a good track record of such, so I was happy and relieved that Aion did not fall short in this department. For anyone that has played WoW, Aion's movement control is 99% identical to it.
Of course, using CryEngine instead of the same old tweaked out Unreal 2 engine certainly helps!
Next up will probably be concerning combat, since movement in Aion ties in closely to combat efficiency.
