Weapon rarity system

Well…I hate the weapon rarity system…I would like the pick a couple of weapons to use as main and upgrade but sice new weapons will drop later with slightly better stats I am not uprgadin any weapon…7 hours into the game still no weapon upgraded.
Decide what weapon system you want looter or upgrade…I would rather have upgradable weapons without the looter rng stat crap…but I could go for looter as well just drop the upgrades and make the base stronger.
