I have deathadder essential mouse. I have fabric mouse pad ( old ). Does mousepad harm or deform my mouses skatez? And my mouse has 2 year warranty. Does Razer's technical service change my mouses skatez in warranty?
On cloth/fabric mousepads your skatez will be "polished" overtime, wear is really minimal.
Hard pads (plastic, aluminum etc) will wear mouse feets more than cloth pads.
There are a lot of really good quality 3rd party mouse feets online like: Tiger Arc/Arc2, Corepad etc.
