Logi mx Master 3s for wow?

How is it? Just got my back a month or so ago and want to potentially replace my g600 since it seems like it’s no longer supported.

Has anyone gone from the 12 buttons on the thumb to just the total 7 buttons of the Mx master? I guess I would have to get used to it but is there a way to rebind some of the other buttons to act as modifiers like gshift or nah ?

I use steermouse and it supports it but was just wondering if anyone can share their thoughts on how cozy/much you can manipulate the buttons. It really looks like an amazingly comfortable mouse to have so wanted to check it out.
