Hat drop rate

[flak dance]

Has the hat drop rate changed?
i Crafted everything i had for a golden wrench and ended up with nothing.

Then i recieve only a few drops since the engy update, then today i get 3 hats in a  row 
ironic as previously i wanted some hats i kept getting kritzkriegs
now i want my kritzkriek back and i keep getting hats :/

crazy

Dunno, but would like to know what limits or averages are in the system that we know about.

Is it worth idling for long?

i crafted all spare stuff i had and got the same hat i had already - a glengarry bonnet. i love my bonnet, but since i only have 2 found hats (got the glove shortly before) i found it quite ironic crafting so many items for the same one... made me facepalm a lot

In my experience the drop system tends to be "when it rains it pours" kind of situation. I also know a guy who had a lucky streak of getting several hats in the one week. Ive been pretty unlucky with hat drops, the only hat I have in fact (non-event that is) is the Miners cap, which I crafted :'( . On the other hand, I recently got a Surgeons mask for the medic so I feel bad for complaining XP.

In my experience.... I found my first hat about 2 years ago.
After that nothing happened for about another year and a half...then I found two hats in the space of 2 months.
I don't think the system is changing, I just think it's a random drop rate, and those who find hats in a row are just the luckiest  bastards around.

EDIT: Ok I failed....but it does seem a long time ago since I got my first hat...even then there was a craze for them when they were only just released.

Hats were only introduced with the sniper/spy update iirc about a year ago.
