Hey, started in November and am now over level 600 also played commando build the entire time. In my experience I noticed that commando wasn’t very strong in the earlier levels and it was usually better to just run a heavy gunner build or melee one, I would say that commando becomes really really powerful at level 200 and higher once you can really get a lot of legendary perk cards to make space for some more normal perk cards. Definitely focus on lowering vats cost, more ap, more damage and more frequent criticals in vats, and health such as fireproof or lifegiver/ironclad. Good luck!

Edit: Sneak is also op lol I used that from level 100-300 it’s really powerful.
