There is nothing more amusing then 5 mages in a party all pushing their fireball button at the EXACT same time, hearing the zooooooooom of the fireball then the explosion.
I present the idea of SpellSync, formerly came to my mind as MageSync.
And I have no idea if it is possible.
Some sort of global timer. The mages (or other class) smash the SpellSync hotkey for that spell. When all 5 mages are all smashing this fireball button, a countdown occurs. Somehow, they are smashing this button but nothing happens. But when this countdown is engaged, and it counts 3, 2, 1, all the buttonmashing mages start casting fireball on the intended target. This timer (possibly communicating with the other mages via a channel) synchronizes all the fireballs when it gets to 1.
Not to mention, this will fix ignite crit damage distribution bug that plagues mages and damage meters.
Well, I thought it was a cool idea. Anyone wanna tackle this beast of an addon?
