Did noone think of the Possibility of SE adding AGI back into the Game? Which could fit for Rogue and Ninja, without messing with the other Stats.

Agility is a synonym for Dexterity. They both mean the same thing. Unless you are meaning something non-standard for AGI it would be kind of repetitive and pointless to add it in.
