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

Sometimes a facepalm just doesn't cut it...

edit:

Look people, what Yoshi-P gave us was an example. You have spells that instant cast that is good for close range combat, and you have high damaging spells that is good for long range. Above that you have debuff. As a mage you have the advantage if you skillfully use your spells and abilities correctly.

all this talk about pvp, its the same concept with pve, except no enmity to worry about.
