For those worried about not being able to hit all your party members with curaga and buffs because they are always moving out of your range.

[dex1206] Magic spells have been unified to strike either a single target or, in the case of AoE, a circular area. Attack range has also been increased, and area of effect broadened.
So this is really a non issue.

Just to reiterate why a change in how we cancel spells is needed, having to select the spell you are casting again in order to cancel it is a bad game design. This is made even more obvious for those of us that use macros, and is further compounded by the animation lock that happens at the start and end of each spell.

Adding spell cancelation from character movement is not the only way to solve these issues, but since no other options that we know of are coming in the immediate future this will definitely work for me.
