What will power (WP) can do for you.

Some champions build AP some build AD and some build health. Champions that want to heal, shield, buff, or CC a little more either have to deal with the stats they are given per level or are forced to build AP. This is inherently a bad thing because not all champions with these effects want to build AP but they do want a stronger effect. My suggestion is that by adding WP champions can build the way they please while still getting strong effects from their "support like" moves. This will introduce a large quantity of new items. Items that are pure WP may go to support players, while AD and WP items can go to top lanes to strengthen their effectiveness in team fights late game. Any combination of these stats will allow more players to build to their champion uniquely and mix up the mundane and repetitive builds of some champions early game.

Just a thought!
