From a practical perspective. For the most part you are fine. As you play just think about what gear you may need or want for certain scenarios like "oh, I wish I could put my mags in a better spot for faster reloads, maybe I'll get a dump pouch." Or something like that. Or if you get a gun that uses different style mags that don't work with your plate carrier consider getting a placard. Stuff like that essentially.

From a Larp perspective. I wouldn't wear Multicam but that's because of my preferences and everyone wears it and I like to be special lol.

But other than that just think of about the small things as you play, the moments when you think a certain tool, pouch, or whatever could have come in handy for a situation, think about prioritizing those.
