The ability of a quality and sometimes pricy gaming keyboard to up your game and improve your damage per second in a game match  is something I value very highly.

There is a very talented Player versus Player guild member of mine by the name of Graril who walked me through how a vertain type of game play called clicking is really ruining everyones quality gameplay.

Clicking is when a gamer consistiently uses only mouse clicks to use abilities in the game.  In any competitive game you have the ability to map different keys on your keyboard to your keys and extra mouse buttons.

You want to map your keys in such a way that you can ergonicly use both hands at the same time to cast or do abilities in the game simultaneously.

Look at it like playing chords on the piano. You want to be able to cast or use up to 10 abilities MAX at once and at minimum do 4 or 5 abilities at once.

This will at worst give you an ability to cast or act on 5 to 9 times as many spells or actions as the newby gamer who still acts by clicking with the mouse.

Im most games the right hand on the mouse also has extra ability keyboard buttons they can depress.

But for your keyboard  you want to recolor your movement keys WASD QE ZXC to a certain set of colors.

And for the gaming keyboard map your action keys a second thrid or fourth set of bright colors to make finind them at night easy to do.

The gaming keyboards I swear by are eith the Corsair or the Razer gaming keyboard.  Find a quality one of either of these brands is not hard. Affording one can be eye opening. 

Both big brands above have individual LED's under each key that allow you to key map each key with a different set of color and abilities.

You can even use the keys to do a different ability each time you hit it, and in fact cycle through a set of abilities in the game while changing the color of the key each time you hit it.

This way the keyboard itself lets you know what ability or spell you are casting by its color and changes as you  cycle through lets say your spell or ability rotation.

Thats a pretty amazing ability for a keyboard. They in fact have a small computer inside the keyboard to manage all this, hence the 100$ ++ price.
