Yeah, of course, PokeMMO stay a MMO you can't get money without farm or without be lucky. This update make the lazy less rich and obliges them to farm.
I'm agree but, the alumet farming is not very long if you are lucky... And if you don't want farming, you can buy it (30k). You can get ~250k from gyms leaders, and you can too beat the richs trainers. So, for me, it's not a bad update.
