When in dealing with Groups of mobs the Red mage was given a move (actually 3 but I'm going to keep this simple for the benefit of the general public)

It's Called Scatter.

in groups of mobs your not meant to be focusing on building up balance really quickly your meant to be aoeing

Scatter has a 25% chance to proc and even more powerful scatter upon hit.

Plus after the first scatter the second scatter is instant because of dual cast

So please when facing groups of mobs if you truly can't be bothered to learn anything about your class. please just press scatter over and over again. It's easy and very hard to mess up and takes less effort than building up balance on one of the many tank's target. plus it makes it a lot easier for the tank to keep hate

and most of all you do more dps.

so please it's 1 button. just keep pressing it. Classes like sam have to 5 buttons correctly to aoe well.

you just have 1. please try
