This is the first game I've ever played where people are begging to be gimped.

There's nothing wrong with the Toggle. It's one of the few features that SE got right with this game. Adding -ga spells is more limiting than a toggle. The current mage classes don't focus on JUST curing, or JUST nuking, or JUST buffin/debuffing, and the toggle makes juggling all of these a lot easier, and a lot more feasible than it would be if we had two - 5 slots being taken up by unnecessary spells.

It sounds to me like people just want -ga spells to foster their XI nostalgia. Stop trying to turn this game into FFXI, kthxbai.
