You providing a grimtools link is the easiest way to help since then we can look at all the details in your gear, stats, devotions, skill tree, and so on. This screenshot you sent us is only showing gear (not even the stats from gear), and the problem might not be there.
So you are playing on your laptop (or your coworker’s laptop, not sure) which does not have access to the internet? Can’t you just use your phone as a router to connect your laptop to the internet? I usually do this when I don’t have access to cable or wi-fi and it is pretty easy.
You could also take a look at any dual wield beginner guide (there are several here in this thread: Beginner build guides Compendium (for AoM + FG expansions)) and compare your stats to what other cold DW melee builds have around this level. Despite being from version 1.1.2.5, I recommend you to look at this infiltrator guide from Nery that looks similar to what you are running: [1.1.2.5] DW cold Infiltrator for beginners-build diary. I believe the only thing that changed is that now there are better MI items available in the game.
I do use Whatsapp, so I could help you there I guess. Send me your phone number by a private message here on the forum and I can add you there.
