Ergonomics. For a gamer who spends many hours on weekends you can't have a mouse that requires you to stretch your hand every few minutes. This is especially important for someone with big hands, pinching a tiny mouse can cause many cramps...
This is a must-have hardware for me, high end sensor technology is what i need because i'm a fast gamer who needs fast mouse that reacts faster to a click of a button & something thats ergonomical too,
Buttons Buttons Buttons, easy to reach yet placed with the right amount of spacing as not to hit more than one button at a time by accident, that make the mouse a monster MMO mouse
Definitely Ergonomic. Needs to fill entire palm otherwise it just doesn't feel right. Sensitivity isn't the end of the world, cause those can be tweaked, but an uncomfortable mouse cannot be fixed. Unless you have a R.A.T.
High End for me... A wireless mouse comes with its own challenges like flat batteries and the like not ideal for some of the situations you find yourself in while gaming online.
I mostly voted for the design but I think that not only the design that makes that mouse cool but it is the whole thing itself. Every thing that the poll has mentioned makes that mouse cool
