Increase the drop rate now plz!!

I love this game but the thing I hate the most is the drop rates for items. Sometimes I farm Co-op and levels over 25 times and finally get the item. But this time I farmed a level over 32 times (This is 100% true cuz I have no life) and thats a lot, well for me. I know that other people want the drop rate to be increased. So Im begging that the creators increase ALL the drop rates for ALL levels and Co-op. Plz tell us how to play add friends too and then I would download the game again
