I am new to L2 just downloaded the game today just got on to try it out befor the 5 hour mainty and i see its click to move will you ever bring out W,S,A,D to move or will it always be click to move :)
You can use WASD to move, just check the "enter chat" box in your options menu. However, L2 was designed as a click-to-move game, so WASD won't work as well as in other MMOs.
Impossible to say whether it will be introduced in a future update or not. But it has been click-to-move for the past 6 years or so, so I'd say probably not.
There is WASD movement at the moment, but it's pretty rubbish. You just have to enable the 'Press Enter to Chat' (or words to that effect) option in the Settings.
You can always use the arrow keys to move around too (pro tip: Towns are packed with player shops, so use arrow keys to move around them whenever possible).
