[Closed] Help me reduce my annual spend on rear mechs please!

I'm running a 1x10 set up with a 11-36t cassette on my Bronson.

I'm getting through rear mechs at a rate of about three a year. I'm always really careful with line choices to try and prolong the life of my mech.

But a stray stick or rock eventually flys up and delivers a fatal blow or like yesterday my chain came off in a race and got dragged into my wheel before I could stop which twisted the cage of the mech. I've been running XT medium cage mechs.

Any suggestions? or should I just start buying cheaper mechs to make it more bearable? My only concern is that an SLX mech might be even less robust.
