The Corsair Scimitar RGB Elite checks a lot of boxes for an MMO/MOBA mouse. Its right-handed ergonomic shape is perfectly suited for palm grip and remains comfortable even during extended gaming sessions. A total of 17 fully programmable buttons are available, including easily spammable main buttons. The software—Corsair iCUE—features a very capable macro editor and allows one to fully customize the Scimitar according to one's preferences. Additionally, the position of the side-button panel can be adjusted, making it quite easy to reach all the buttons no matter one's hand size. Furthermore, the Scimitar RGB Elite features an impressive set of RGB lighting, which again is highly customizable within the software. While neither sensor performance nor click latency are of the highest relevance for MMO and MOBA games, the Scimitar RGB Elite does very well in these departments too. Coupled with a solid build, good materials, nicely gliding feet, and a grippy coating, the Scimitar RGB Elite is a great MMO/MOBA mouse.
There are some caveats, however. While the software is very capable, it's also a bit of a resource hog. For what it's worth, make sure to keep iCUE minimized to keep RAM usage under control. It's not really intuitive to navigate, either, and some functions (such as saving changes to onboard profiles) can appear convoluted at first. Although button quality is always subject to manufacturing variance, my sample at least had a side button that was of notably poor quality. Finally, for those who want to occasionally play an FPS with their MMO mouse, the Scimitar RGB Elite is less than ideal. The cable is very stiff, the weight high, and the wide body coupled with the side-button panel make it difficult to get a firm grip. It's a bit of a shame actually because both the sensor and click latency would make the Scimitar RGB Elite a great fit for FPS as well otherwise.
So all in all, while not perfect, the Corsair Scimitar RGB Elite is a very good MMO/MOBA mouse, and gets a Recommended from me.
