Why the hell did plarium cut the time to farm them down.Recently i counted over thirty invader and ghost tiles some had been farmed some others not even touched all unavailable.This pissed me off so bad i am seriously considering quitting all plarium games.I have spent a lot of money buying packs to be able to kill them not any more if the money hungry ass holes wont give us 12 hours to farm what  we kill piss on them.I will spend my money on something plarium has nothing to do with. They rope you in with you can play for free then screw you every way possible do not take a way what the game started with
