ALL I GET IS POKE BALLS!?

Make sure you don't run out...there is a theory (it might just be my theory) that the more you have of something then the more you get.
So if you let something run out, you will find it hard to get more of that item.

It is a great system if you are collecting a lot of something...it gives more of what you are collecting.

But when you run out, that same algorithm works against you...giving you what you already have, and not what you need to replenish.

TL/DR Never let something important run out...because the more you have, the more you get.

Over the last 2 weeks, I have noticed that I get way more balls than potions/revives. My potion/revive invetory went from more than 100 each,(where I like to keep it) to less then 50 each, and I have not changed my game paly at all.

This was 100% the case for me. The week or so was rough for potions. Barely any.

I was out late last night though and they started to finally come. See if things are changing now but I definitely noticed it too.

If you're spinning almost 1.5 pokestops per minute, I wouldn't worry about potions eventually showing up.

I've noticed a reduced potion drop rate. I suspect it's because they want you collecting critters instead of battling. They DO drop... just at a much slower rate.

i am almost out of revives. fine with potions. tons of balls. In my opinion they are discouraging fights so players kept out of gyms will be forced to spend real money during the easter event, which is likely to have special packs in the shop like the Xmas event had...

...or maybe you will need a ton of pokeballs for a the easter event itself :)
