That mouse is about 9 or so years old, according to articles/reviews made about said peripheral. Since then a lot has changed and the peripherals that are available now will either have a macro bank in place of a higher and lower row of side buttons or just one row(located above) due to a better understanding of what ergonomics for the hand is...like the Razer Naga Pro, the Logitech G600 or just about any MMO mouse on the market are probable candidates for what you're looking for.
Roccat NYTH is also another nice one that is actually customizable for the buttons, but harder to find and expensive.
My favorite mouse of all time for button placement is hard to find and expensive, the Steelseries WOW Legendary mouse. For some reason no one made that shape with the cross button layout on the side or the two buttons on the sides of the wheel, or the pinky button. Just a perfect placement and amount of buttons I think. I owned two of them, but kids managed to damage the buttons on both https://www.amazon.com/SteelSeries-World-Warcraft-Legendary-Gaming/dp/B005L38QHA
