Design
The length of the mouse is a bit shorter than what I'm used to, but extremely close to previous versions of SteelSeries' MMO mice. Since I tend to place the bottom edge of my palm on the very back of the mouse, my hand is positioned naturally in a mild form of a claw grip. The scroll wheel is in the direct middle of the mouse, equipped with a single-click. The raised border to the left and right of the wheel also each serve as an additional button, with another larger, single button at their base. This totals four unique, programmable buttons just in the scroll wheel area alone.
The mouse is guided using the thumb and ring-finger on either side, grasping the mold to control hand movements. We commonly see two customizable buttons placed directly above the thumb as we do with the Legendary, though they can sometimes be hit or miss. In my case, the rear of the two buttons is extremely easy and comfortable to reach with the thumb, while the front button requires a slight shift of the entire hand to reach comfortably.
In addition to these two horizontal buttons, SteelSeries has also installed two vertical buttons that line up perfectly with the natural rest of my thumb, creating somewhat of a directional pad between all four. Though these are extremely accessible, the fact that they are positioned directly with the thumb rest means they are easy to press on accident.
My favorite button is on the opposite side of the mouse. The Legendary edition is also a bit wider than the common mouse, which allows for a lip on the right-hand side for the ring finger to rest on. This also allows for yet another customizable button directly under the ring finger. Since this button is on a level surface (as opposed to on the side of the mouse), it requires actual effort instead of an accidental nudge to activate. For those of you keeping track, this is our eleventh (and final) programmable button.
The bottom of the mouse is fairly typical, equipped with two ceramic feet near the bottom and one at the top to ensure a smooth glide on a wide variety of surfaces.
The remainder of the physical design is more of a homage to World of Warcraft fans. The most notable trait is the glowing WoW logo, which pulsates and can be set to any color on a 16.8 million palette. This lighting does have a practical application of easily indicating which of the ten profiles is currently selected. For instance, my Warrior profile is a red glow while my Mage is a blue. Since one of the customizable face buttons can be set to switch profiles on the fly, it's a handy visual tool to guide you to the desired profile (and if accidently hit, may explain why your DPS rotation isn't working).
The pulsing logo and the splintering lightening graphic around it was inspired by an actual in-game item, the Thunderfury. This sword, according to Warcraft lore, is equipped with a talisman that contains the essence of the Prince of Air, Thunderaan. That talisman is unmistakable in-game, a bright glowing orb just above the hilt of the sword. The pulse-globe on the Legendary Edition MMO mouse has the same effect while sitting on a gamers' mouse surface. The Thunderfury is of course a Legendary sword, denoted by the same orange font that attracted me to SteelSeries' packaging.
