Hey all, I been commuting by my MTB for a while and I love it. One issue though the gearing is not optimal for the terrain I ride or how I like to ride it. My current crank is stock (FSA Alpha Drive 42/32/22) my problem is that I never use the smallest ring and the tallest is not tall enough for me. What are my options? Any suggestions? I would like my tallest to be my mid ring my mid to become my lowest and something taller for downhill’s. I am sorry I am new to working on my own bike so I am not sure what I can do and if it's even worth it. I have plenty tools at home as I work on my own cars most of the time, I don't mind buying bike specific tools as I am gear head and more toys to play the better . Any advice?

Specs for my bike you can find it hear:

I know this is not perfect commuter bike, I bought it with intention of replacing my old MTB and XC riding but I found that commuting is more fun, healthier, to some extend safer, and very rewarding. So any help would be appreciated.
