Leave it as it is.

Watch those aoe's. Pull mobs to where you want to fight them.

Basic stuff like that.

They obviously did not want mass training of mobs and aoe farming in this game. Fair enough.

The game is easy enough as it is without simply being able to area nuke with impunity and full benefits.

I suspect the people asking to have it changed to the old style are either very lazy, or running an RMT team.

I bet you are more careful when the mobs that might add are much higher rank or an NM.
