I guess I'm an exception, then.
I tend to play 1 weapon at a time, and play pretty much only that weapon for that period of time. So I have a lot of 4 stars.
The 3 stars are the weapons that didn't
quite last me long enough to get 4 stars but most of them are almost there. Because of this, sometimes I'll go back and spend a day or two on a weapon like that just to get 4 stars on it to officially add it to the collection of weapons I've played.
I don't have very many 2 stars, but they're all weapons that I tried out and then I ended up going back to what I was playing before.
The 1 stars are mostly alternate kits that I didn't end up liking as much, although there are a few exceptions.
Tiers are ordered by freshness (so machine is almost 4 stars, for example)
