What does your character rank or overall rank do for you?

I know this is a test build, but, i’m curious what the intended use is, since I see nothing being modified by my rank, and i’m not rewarded with anything, so it just seems like an arbitrary number.

Overall rank unlocks other rarity packs for purchases

I think mostly prestige besides unlocking the lou dout packs.

Every five levels of your command rank you get a random(?) commander pack which has some gear and a guaranteed faction skin or taunt.

Character ranks unlocks new helix mutations, skins and at lvl 15 you also get a taunt. Some of the character levels, not sure which, but the ones that don’t give you a mutation/skin, also give you loot packs.
