They should add the following Orders.

"Go To A" "B" "C" "D" Basically the command with dis-engage and cause the allies to gather in one location

"Focus 1" "2" "3" "4" "5" Same as above but it will force the allies to engage the target with the proper number, if number is not active it will act just like the Order Button.

I think those basic changes would help when it comes to dealing with AOE. I'd rather take 30 second using waymarks and signs to better order the party then deal with the hassle of nearly wiping because of their derpiness lol.
