It really was such a good mouse. Lasted like 8 years for me before I went for a Steelseries Rival 500 which was the closest I could find in button configuration. But now that's discontinued too...
Rog Sparta. Owned mine for over a year and I like it a lot. I needed something to replace my Rival 500, aka the best mouse ever made.
Steel Series Rival 500 is the best mouse i have tried for mmos, has a lot of buttons but they are ergonomic, each button has a different shape and position so it's easier to tell what you are pressing, way better than the Logitech g600.
peak (swiftpoint z2) mentioned! other than this, i also own steelseries rival 500, EVGA x15 (and while its mainstream, cant forget the og Logitech g502). Runner up that id love to own is the godawful abomination Elecom M-dux70bk. Theres also a really nice DIY open source mouse, called lynxware im primarily an mmo mouse enjoyer so weights and size doesnt matter to me
[mice with more than 5 buttons ](https://www.eloshapes.com/mouse/browse?side_buttons=5,12) You can adjust the filter more if you'd like. I personally use a steelseries rival 500 when I need multiple buttons but that mouse has been discontinued a long time ago.
I don’t have a traditional mmo mouse with the full numpad, I’ve always opted for something with 5 or 6 side button located round the thumb and a rest spot. They are super easy to get used to, however I played stuff like dota/lol with them before I started gw2 I have always opted for main skills on mouse and utility etc on the keyboard round wsad, 1-4 cxz for example, however I’ve always struggled with modifiers (ie shift + 2 being different to 2) so having unique keys for actions is important to me. Overall for comfort of mouse use I’d definitely recommend a mouse with a thumb rest on the side. I loved the steel series rival 500, however I think they discontinued it, so I don’t really have a recommendation atm
