Moving will be made to interrupt spellcasting at a point in time...

all i said was this is what i think of. it is moving during casting. you tried to say it didn't happen in harry potter and they stayed still. i show you and now you change your excuse. i'll bet more people relate to how mages move in harry potter than the people that still think like dungeons and dragons where they stand still the entire time.

images of fantasy characters such as mages have evolved over the years and so have the games that use them. using something that is in a 10 year old game because that's how it was then isn't a good excuse for why it is done later on.

they thought the world was flat years ago as well, but people have long moved past that.

I think movement while casting is bad both from a game mechanics as well as flavour (or believability, if you wish) perspective. First of all, why would anyone ever bother learning to wield a weapon if you could just flick your wrist and have a fireball come out of your fingertips? Making magic not seem completely overpowering against traditional arms is a challenge as it is. Those enormous explosions BLMs throw around would be quite ridiculously omnipotent if their casting was trivialized like that. I enjoy magic that is immensely powerful and without bounds in what it can do but limited by its difficulty. That's essentially what D&D magic is (especially 2nd edition) and spell casting in video games has never been as epic as it was in Baldur's Gate 2. Want to stop the very flow of time? How about summoning a meteor shower? Turn a dragon into a squirrel? Drain the moisture out of a whole group of guys? Turn invisible? Reflect hostile magic? Tear down magical protections? Transform into a troll? You can do all that and more, so much more! But if a guy with a sword catches you without your protections up, you go down instantly. That's the price you pay for wielding godlike powers.

Moving while casting is also a huge can of worms for game balancing. When you mix guys with only melee attacks with guys who can run at full speed while functioning at full capacity at range, you'll easily find yourself in treacherous waters. Mages in other MMOs like WoW and Rift are very limited in what spells they can cast while moving and they still often end up dominant in certain 1v1 matchups against non-casters. It has PVE implications as well as mobs without ranged attacks are almost always very poorly equipped to deal with kiting opponents.
