Illidan     4,000       6,49         Assassin    World of Warcraft

And I want to query a select of 5 different roles and 5 random names i.e. this:

name        role
----------  ---------
Sylvanas    Specialis
The Lost V  Specialis
Azmodan     Specialis
Zagara      Specialis
Murky       Specialis
Johanna     Warrior
Anub'arak   Warrior
Chen        Warrior
Arthas      Warrior
Stitches    Warrior
The Butche  Assassin
Kael'thas   Assassin
Thrall      Assassin
Jaina       Assassin
Tychus      Assassin
Lt. Morale  Support
Kharazim    Support
Reghar      Support
Brightwing  Support

I tried using Limit but that only gives the first 5 elements of the table.

What to do?
